After Clint Eastwood and Don Siegel came on-board the project, they hired Dean Riesner to work on the script. In his first re-write, the bank robbery scene ends with Harry not pointing the gun at the robber, but placing it against his own temple. He pulls the trigger, laughs, and then walks away. Eastwood and Siegel both felt this was too extreme, even for Harry Callahan.

Serial killer Scorpio was loosely based on the Zodiac killer, who used to taunt Police and media with notes about his crimes, in one of which he threatened to hijack a school bus full of children. The role of Harry Callahan was loosely based on real-life detective David Toschi, who was the chief investigator on the Zodiac case.

After this movie was released, Andrew Robinson received several death threats, and had to get an unlisted phone number.

The Scorpio Killer (Andrew Robinson ) wears a belt with a peace symbol buckle throughout this movie. According to producer and director Don Siegel, "It reminds us that no matter how vicious a person is, when he looks in the mirror he is still blind to what he truly is."

Andrew Robinson created a backstory for Scorpio which involved him being drafted into the Vietnam War, and seeing unspeakable horrors. When he returned home to the United States, he found himself a figure of hate, and his war experiences, combined with the people's treatment of soldiers, caused him to go insane.

When Clint Eastwood approached Don Siegel to offer him the directing job, Eastwood gave Siegel four drafts of the script, one of which was written by Terrence Malick. In Malick's script, he had altered Scorpio from being a mindless psychopath killing only because he likes it, to being a vigilante who killed wealthy criminals who had escaped justice. Siegel didn't like Malick's script, but Eastwood did, and Malick's ideas formed the basis for the sequel, Magnum Force (1973).

The original draft of the script by Harry Julian Fink and Rita M. Fink was set in New York City. When Clint Eastwood and Don Siegel became involved in the project, they initially planned to relocate this movie to Seattle, Washington before ultimately deciding on San Francisco, California.

Such was the success of this movie that Clint Eastwood and Don Siegel found themselves invited to address police gatherings.

As is well-known, Clint Eastwood directed the scene with the suicide jumper (Bill Couch). However, it is often claimed he directed the scene only because producer and director Don Siegel was ill. This is inaccurate. Siegel was indeed ill, and wasn't on the set, but Eastwood had always been scheduled to direct that scene, due to the difficult logistics of getting the actors, director, cameraman and sound man all together on the top of a small ledge. In the shooting schedule, six nights had been set aside for the shooting of the scene. Eastwood told the studio he could shoot it in two nights. In the end, he shot the entire scene in one night.

Andrew Robinson was cast at the behest of Clint Eastwood, who had seen him in a Broadway production of Fyodor Dostoevsky's "The Idiot". Eastwood then convinced producer and director Don Siegel that Robinson had the right unnerving characteristics to make an effective Scorpio.

This movie's most famous line is often misquoted. A lot of people mistakenly quote the line as "Do you feel lucky, punk?", while the actual line is "You've got to ask yourself one question: 'Do I feel lucky?' Well, do ya, punk?"

(At around ten minutes) In the bank robbery scene, Harry enters a burger joint across the street from the bank. Around the corner from the burger joint, the viewer can see a movie theatre marquee that lists Play Misty for Me (1971). Clint Eastwood starred in and directed that movie, which was the first theatrical movie directed by Eastwood.

Unlike most other municipal police organizations, the San Francisco Police Department calls their detectives "Inspectors". Hence, the title character's official rank and name is "Police Inspector Harry Callahan", and not "Detective Harry Callahan". This was especially confusing for audiences in countries using the British Commonwealth police ranking system where "Inspector" was a rank equivalent to a U.S. Lieutenant.

When Universal Pictures allowed its option on this movie and characters to lapse, Warner Brothers purchased the rights with a view to cast Frank Sinatra. Sinatra was interested, however, he had broken his wrist during the filming of The Manchurian Candidate (1962) and during contract negotiations, he found the large handgun too unwieldy. Additionally, his father had recently passed away, and Sinatra decided he wanted to do some lighter material. After Sinatra dropped out, Warner Brothers considered Marlon Brando for the role, but never officially approached him. Next, they offered it to Steve McQueen and then Paul Newman, both of whom turned it down (McQueen didn't want to do another cop movie after Bullitt (1968) and Newman felt the movie was too right-wing). Newman however suggested Clint Eastwood as a possible star.

The Smith & Wesson .44 Magnum used in this movie is now owned by prop master and weapons specialist Bill Davis, who bought it off of the production company several years before this movie became popular. The revolver is still in use as part of his catalogue.

Andrew Robinson (the Scorpio Killer) claims to have ad-libbed the line "Hubba, hubba, hubba, pig bastard" while taunting Harry on the phone.

A Police Department in the Philippines ordered a print of this movie for use as a training film.

The idea of a car chase was dropped as another cop thriller set in San Francisco, California, Bullitt (1968), had already set the bar for that. The car chase was used in the subsequent Dirty Harry sequels Magnum Force (1973), Sudden Impact (1983), and The Dead Pool (1988).

Albert Popwell appeared in every "Dirty Harry" movie except The Dead Pool (1988) playing a different character in each movie.

Clint Eastwood agreed to star in this movie only on the proviso that Don Siegel direct. Siegel was under contract to Universal Pictures at the time, and Eastwood personally went to the studio heads to ask them to "loan" Siegel to Warner Brothers. Eastwood has always maintained in interviews that the reason he took the role was because he felt the issue of victims' rights was being ignored in the political arena at the time, and he thought this movie could be a good way to bring it more to the fore (which it did).

This movie's line "You've got to ask yourself one question: 'Do I feel lucky?' Well, do ya, punk?" was voted as the number fifty-one movie quote by the American Film Institute (out of one hundred).

All the outdoor scenes were actually filmed in San Francisco except for the bank robbery which Dirty Harry foils, when he first utters his immortal phrase, "'Do I feel lucky?' Well, do ya, punk?" This scene was shot on a set.

A close-up shot was planned for Debralee Scott's appearance, in which she played the nude corpse of Ann Mary Deacon. She felt so cold in the dawn chill that she shivered uncontrollably. After several failed takes, her scene was filmed as a long shot.

DIRECTOR CAMEO (Don Siegel): Pedestrian walking past Harry's (Clint Eastwood's) car when he and Chico (Reni Santoni ) return to Police Headquarters.

This movie makes references to the then-recent criminal court trials of Escobedo v. Illinois and Miranda v. Arizona. Escobedo v. Illinois was a 1964 case which ruled that any statements made by a suspect without the presence of legal counsel were inadmissible as evidence. Miranda v. Arizona was a 1966 case which ruled that a suspect had to be informed of his or her rights prior to interrogation. If he or she was not informed of his or her rights, the subsequent interrogation was deemed null and void.

Arnold Schwarzenegger, and Robert Urich cited the character of Harry Callahan as being one of the biggest influences on their careers. Schwarzenegger said watching this movie inspired him to seek out action roles with wisecracking heroes who were a law unto themselves. Urich based his portrayal of Dan Tanna in Vega$ (1978) on Clint Eastwood's performance in this movie, especially his tendency never to get angry or raise his voice. According to Urich, when shooting the pilot, he was very consciously doing an impression of Eastwood, having worked with him in Magnum Force (1973).

The Scorpio Killer's real name is never revealed through out the entire movie, and in the ending credits, he is simply listed as "killer". However, after this movie's release, a novelization gave his real name as Charles Davis.

This movie helped popularize the Smith & Wesson Model 29 .44 Magnum revolver, which experienced an upswing in sales following this movie's release.

When Don Siegel was hired as director, he was considering Audie Murphy for the role of the Scorpio Killer. Siegel thought it would be a nice irony to have a genuine war hero and heroic screen icon known for playing clean-cut characters playing a psychopathic killer. Siegel offered Murphy the role, but Murphy died in a plane crash on May 28, 1971 prior to making his final decision.

Andrew Robinson remarked in an interview many years later that he didn't understand how to read a movie script. This was due to his having been a theatre actor all of his career, until cast in this movie.

When Composer Lalo Schifrin was scoring this movie, he told producer and director Don Siegel that he wanted to use female vocals for the scenes with the Scorpio Killer in them. When Siegel asked him why, Schifrin replied that he believed Scorpio was conflicted about what he was doing as he wore a peace symbol belt buckle, yet he was a murderer. Schifrin believed that Scorpio heard voices in his head and the female vocals would represent that. (This particular score was later sampled by rap group NWA in 1991 for their song "Approach to Danger".)

Theatrical movie debut of Andrew Robinson (the Scorpio Killer).

This was the first theatrical movie portraying the San Francisco Police Department's Bureau of Inspectors' Homicide Detail. The success of this movie led to the development of the television show The Streets of San Francisco (1972).

Banned in Finland for over a year.

When producer Jennings Lang initially could not find an actor to take the role of Callahan, he sold the movie rights to ABC Television. Although ABC wanted to turn it into a television movie, the amount of violence in the script was deemed too excessive for television, so the rights were sold to Warner Brothers.

Robert Mitchum turned down the lead role, calling this, "a film I would not do for any amount." Mitchum's younger brother John Mitchum appeared in the first three movies as Inspector Frank De Giorgio.

According to the original script, the phrase that Dirty Harry quotes during the bank robbery and his final confrontation with the Scorpio Killer was not the actual quote for the movie, the actual quote in the script was, "Well? Was it five or was it six? Regulations say five...hammer down on an empty...only not all of us go by the book. What you have to do is think about it. I mean, this is a .44 Magnum and it'll turn your head into hash. Now, do you think I fired five or six? And if five, do I keep a live one under the hammer? It's all up to you. Are you feeling lucky, punk?"

When Harry Callahan breaks into the Groundkeepers quarters, the centerfold on the wall is March 1967 Playmate of the Month, Fran Gerard.

The gun the Scorpio Killer stole from the liquor store owner was a 9mm Walther P38. During his rooftop shoot-out, he used a German MP40 submachine gun. The sniper rifle he used was a 7.7mm Japanese Arisaka Type 02 Paratrooper Takedown rifle (rechambered in .30-06 Springfield) fitted with a suppressor. This particular rifle was sporterized. All of the Scorpio Killer's weapons were World War II-era infantry weapons used by the Axis forces. Harry's guns, a Smith & Wesson .44 caliber Magnum and a Winchester rifle were, by contrast, wholly American.

The opening sniper scenes were shot from atop San Francisco's Bank of America Building located at 555 California Street. The sniper's target is a girl swimming in the pool on the roof of the then-Holiday Inn Chinatown, located at 750 Kearny Street, and since about 1995, renamed Hilton San Francisco Financial District. 750 Kearny Street is located on a straight line five blocks north (about one thousand six hundred to one thousand seven hundred feet) of the Bank of America Tower. Since the Bank of America Tower is considerably taller than the hotel, the vantage point is looking down at the rooftop pool at the hotel, and would be a relatively easy shot for a trained marksman. Since the Hilton take-over of the hotel, the pool is no longer open or operable.

One of the reasons why Don Siegel cast Andrew Robinson as the Scorpio Killer was because he wanted someone "with a face like a choirboy".

The bridge off of which Callahan jumps, landing on the roof of a schoolbus (in Larkspur, California), was torn down in August 2003 after being damaged by a truck two months earlier.

Was amongst the U.S. Library of Congress' selections for preservation in the National Film Registry archives in 2012.

In a 2009 poll for MTV News, the character of Harry Callahan was voted the "Greatest Movie Badass of All-Time". Dirty Harry beat other movie icons like Rambo, Ellen Ripley, and John McClane to the top spot.

One evening Clint Eastwood and Don Siegel had been watching the San Francisco 49ers in Kezar Stadium in the last game of the season and thought the eerie setting would be an excellent location for shooting one of the scenes where Callahan encounters the Scorpio Killer.

In the opening, when the memorial wall with the names of SFPD officers killed in the line of duty is shown, the name "Eric A Zelms" is shown. Zelms was one of two SFPD officers who likely saw and possibly spoke to the infamous Zodiac Killer on the night of October 11, 1969 as they responded to the Zodiac Killer's murder of cab driver Paul Stine in the Presidio Heights area of San Francisco. As Zelms and his parter Don Fouke were driving towards the murder scene, they encountered a lone caucasian male walking away from the direction of the crime scene. Since the initial and erroneous police description of the murder suspect was a "black male", Zelms and Fouke let the man proceed on his way. Later when the police description of the murder suspect was corrected to a "white male", there was much speculation that Zelms and Fouke had encountered and possibly spoken to the actual Zodiac Killer as he fled from the murder scene.

Burt Lancaster turned down the lead role because he strongly disagreed with the violence of the story and with what he perceived to be its "right-wing" morals.

When Frank Sinatra and Irvin Kershner were still attached to the project, James Caan was under consideration for the role of the Scorpio Killer.

The original title was "Dead Right".

Uncredited screenwriter John Milius wrote his draft of this movie inspired by Akira Kurosawa's studies in lone-gun detectives, while producer and director Don Siegel tackled the material from the viewpoint of bigotry.

The shoes that the Scorpio Killer wore were Corcoran Jump Boots that are worn exclusively by Army Paratroopers.

The first of six Clint Eastwood movies shot in his birthplace of San Francisco. Eastwood grew up in nearby Piedmont, and for part of the 1970s was living in upscale Tiburon in Marin County.

Lalo Schifrin's score is on The American Film Institute's list of The 250 Greatest Film Scores of All-Time announced in 2005.

Initially, Warner Brothers wanted either Sydney Pollack or Irvin Kershner to direct. Kershner was eventually hired when Frank Sinatra was still set to star, but when Sinatra dropped out, so did Kershner.

All of the blanks for Harry's gun had to be made especially for this movie, as the standard 5-in-1 blanks used in most movies do not fit a Smith & Wesson .44 Magnum chamber.

"Dirty Harry" is the slang term for a photographer (either shooting paparazzi and/or modelling shoots) with a single lens reflex (SLR) camera. The slang term for an SLR camera is a .44 Magnum.

Critics initially disliked this movie as they objected to police brutality.

The movie's line "You've got to ask yourself one question: 'Do I feel lucky?' Well, do ya, punk?" was voted as the number fifty-one movie quote by the American Film Institute of all time. However, if one reads Harry's lips, you can see that Clint Eastwood says "buck" rather than "punk". "Punk" was looped in in post-production because the term "buck" is an offensive term for a male African-American.

Dirty Harry's gun is supposedly a Smith & Wesson Model 29 revolver, chambered for a .44 Magnum cartridge. In this movie, the gun is shown as being capable of sending assailants flying through the air, even when shot from a distance, however, in reality, the gun does not produce such dramatic results. Additionally, the .44 Magnum round is not considered to be a practical caliber for urban police force use due to recoil (which makes target re-acquisition difficult) and over-penetration issues, which greatly increases the likelihood of the bullet going through its target and injuring bystanders. (Harry, of course, is a renegade officer, and presumably the .44 is his own gun, not police property.) The actual gun used on set by Clint Eastwood was in fact a Smith & Wesson Model 29. It is a common misconception that a Model 29 could not be located, and a Model 57, chambered in .41 Magnum, was used instead. Clint Eastwood contacted Bob Sauer, representative for Smith & Wesson, to acquire the pistol. The Model 29 had been in production up until the late 1990s, but several pistols were assembled from parts at the factory, and provided to the crew. Eastwood took one to a firing range to familiarize himself with the Model 29.

Oprah Winfrey visited Clint Eastwood in 1997. Oprah interviewed Eastwood's family, she asked his mother Ruth Wood, (then eighty-eight at the time), what her favorite of her son's movies is, she replied, "Dirty Harry (1971)". Oprah's reaction was, "Really?!"

Contrary to some sources, John Wayne was never offered this movie due to his age. He later starred in his own cop movies, McQ (1974) and Brannigan (1975).

Despite Kezar Stadium being home to the 49ers, the Scorpio Killer has a pennant for the Oakland Raiders in his makeshift apartment. This is visible when Harry searched the apartment. The Oakland Raiders played part of their inaugural season in 1960 at Kezar Stadium.

In the opening scene, the camera pans over Market Street, and a bulldozer can be seen driving up Powell Street. This was due to the construction of the Powell Street BART (Bay Area Rapid Transit) station. Construction continued all through this movie's shooting.

Glenn Wright, Clint Eastwood's costume designer since Rawhide (1959), was responsible for creating Callahan's distinctive old-fashioned brown and yellow checked jacket to emphasize his strong values in pursuing crime.

In the scene where Scorpio pays the guy $200 to beat him up equals about $1300 (as of 2021). He paid for seven hits plus one "on the house". Coming to $28 ('71) per strike or $185 (2021).

Lee Marvin turned down the lead role.

"Dirty" Harry Callahan ranked number seventeen on The American Film Institute's list of The 50 Greatest Movie Heroes of All-Time announced in 2003.

In his 1980 interview with Playboy, George C. Scott claimed that he was initially offered the lead role, but the script's violent nature led him to turn it down.

John Milius owns one of the actual Model 29s used in principal photography in this movie and Magnum Force (1973). As of March 2012 it is on loan to the National Firearms Museum in Fairfax, Virginia, and is in the Hollywood Guns display in the William B. Ruger Gallery.

One of this movie's biggest fans was "Carry On" regular Kenneth Williams, who wrote about it at great length in his diaries.

When Callahan is being run all over town by the Scorpio Killer, he passes a wall which bears the graffiti "KYLE", the name of one of Clint Eastwood's sons, Kyle Eastwood (now an internationally acclaimed jazz musician), who was three-years-old at the time.

Harry drives a 1968 Ford Galaxie 500, California plate "WKH 370".

The first of five movies starring Clint Eastwood as Inspector "Dirty" Harry Callahan.

Smith & Wesson was actually considering discontinuing production of their Model 29 .44 Magnum revolver before this film boosted its popularity. Each film in the Dirty Harry series prompted a surge in sales of the Model 29. Many of these pistols would show up for sale at used gun dealers just a few months later, after the buyers discovered how uncomfortable it was to shoot the high powered .44 cartridges.

Doris Day said in an interview in 1993 on Vicki! (1992), which took place in Ms. Day's home of Carmel-by-the-Sea, California, said that Clint Eastwood was one of her neighbors. When asked what her favorite Clint Eastwood movie was, she replied "Dirty Harry (1971)". N.A.T.O., (The National Association of Theatre Owners), named Doris Day number one on their list of the Top 10 Box-Office Stars in the world a few times back in the 1960s. Clint Eastwood made their list several times in the 70s, 80s, and 90s.

Theatrical movie debut of Josef Sommer (District Attorney William T. Rothko)

Uncredited theatrical movie debut of Richard Lawson (Homosexual).

Included amongst the American Film Institute's 1998 list of the four hundred movies nominated for the Top 100 Greatest American Movies.

In the pool scene at the beginning of the movie, the pool seen on the rooftop is the same as the one Clark Griswold played with while at work in National Lampoon's Christmas Vacation (1989).

This movie ranked number forty-one on The American Film Institute's list of The 100 Greatest Thrillers of All-Time, announced in 2000.

In the scene where Harry Callahan breaks down the door of scorpio's Kezar Stadium room there is a pendant hanging off one of the lockers for the Oakland Raiders. The Oakland Raiders played one season at Kezar Stadium when they were with the AFL. Kezar Stadium was also the home for the San Francisco 49ers prior to moving to candlestick park.

John Wayne received the script through his Batjak production company, but passed, feeling it was too gratuitously violent. He also objected to getting a role that Frank Sinatra was offered first, but declined. He said later that he made a mistake, cited the role would ultimately have been a good fit for him and made two Dirty Harry-type movies, McQ (1974) and Brannigan (1975), later on as a result.

This movie arose when public concern about the political situation in the United States grew, in particular, the Vietnam War and the Watergate scandal. This undermined public confidence in the laws and political structure. This is reflected in this movie: so the main character denotes his opinion to the laws in force, calling them crazy.

Debralee Scott 's debut,

The Scorpio Killer's rifle was a 7.7 Arisaka Type 2 Paratrooper Takedown rifle fitted with a Hiram and Maxim suppressor, chambered in .30-06.

Inspector Harry Callahan's badge number is 2211. His radio ID is 71.

Included amongst the "1001 Movies You Must See Before You Die", edited by Steven Schneider.

"Dirty Harry" was used as the title of a song by the band Gorillaz in their album Demon Days (2005).

Rita M. Fink created the character of Harry Callahan.

Reni Santoni and Andrew Robinson appeared in Cobra (1986).

The police helicopter was a Bell 206.

This is the first time Inspector "Dirty" Harry Callahan (Clint Eastwood ) says to a partner "Welcome to homicide" after Chico Gonzalez (Reni Santoni ) sees the dead boy killed by the Scorpio Killer. The only other Dirty Harry movie he uttered the phrase was in The Enforcer (1976), after Inspector Kate Moore (Tyne Daly ) runs out on the gas company guard's autopsy.

The iconic "Do ya feel lucky, punk?" speech was not written by any of the credited screenwriters but by script doctor John Milius.

While Debralee Scott plays Ann Mary Deacon's naked corpse, she is not the same actress featured in the photographs at the police station; the actress in the photographs was Melody Thomas Scott.

Before the bank robbery when Harry is crossing the road toward the deli, in the background the cinema is advertising Play Misty For Me

The sniper calls himself "Scorpio", which is the Zodiac sign for people born between October 24th and November 22nd. November 22, 1963 is the date that former President John F. Kennedy was assassinated by a sniper in Dallas, Texas, a killing in which Clint Eastwood's character in In the Line of Fire (1993) was directly involved.

Count the number of VW Beetles on San Francisco's roads - surely a nod to Bullitt.

Angela Paton's debut.

Included among the American Film Institute's 2001 list of the top 100 Most Heart-Pounding American Movies.

The short-lived Boston punk band Klover titled their 1995 debut album "Feel Lucky, Punk?"

The Scorpio Killer's sniper rifle was a 7.7 Arisaka type 2 Takedown rifle fitted with a Maxim & Hiram suppressor.

In the school bus, the Scorpio Killer and the children sing two popular children's songs, "Old MacDonald Had a Farm" and "Row, Row, Row Your Boat".

Motion Picture Association of America (MPAA) approved, no. 23049.

While held hostage in the school bus, the Scorpio Killer and the children sing two popular children's songs, one which is "Row, Row, Row Your Boat". That is the same song the children sing in Die Hard with a Vengeance (1995) in the school auditorium while held hostage.

Kate Harper's debut.

When Harry's badge and police license are shown, his name reads as Harry Callahan. No middle initial. And, it suggests that Harry is not a nickname for Harold.

When Harry finally meets Scorpio in Mount Davidson Park, Scorpio orders him to show his gun with his left hand. Harry pulls it from his holster and Scorpio ad-libs the line, "My, that's a big one!" This line caused the crew to crack up and the scene had to be re-shot, but the line stayed.

The final scene, in which Harry throws his Police badge into the water, is a reference to a similar scene in Fred Zinnemann's High Noon (1952), was a cause for a disagreement. Clint Eastwood, who had a sequel in mind and didn't want the character to quit, objected to the end of this movie when Harry throws his badge away after killing the Scorpio Killer, arguing with Producer and Director Don Siegel that Harry knew that being a policeman was the only work for which he was suited (and indeed the sequel Magnum Force (1973) begins with Harry still on the force, with no indication that he ever quit), so, Eastwood refused to show up to work for most of the day to film it. Siegel, however, always saw Callahan as a borderline vigilante and argued that in this way, Callahan showed his disdainful attitude towards the bureaucrats who sat in the Police Department. Siegel eventually convinced Eastwood that Harry threw his badge away as a symbol that he had lost faith in the justice system.

Clint Eastwood performed all of his own stunts, including the stunt where he jumps onto the roof of the hijacked school bus from a bridge. His face is clearly visible throughout the shot.

When the Scorpio Killer is running away from Callahan at the end of this movie, he spots a young boy sitting near a pond, and grabs him as a hostage. The kid was played by Andrew Robinson's real-life stepson Stephen Zacks.

In 1972, a copycat crime took place in the state of Victoria, Australia, in which two men kidnapped a teacher and six pupils at gunpoint and demanded a $1 million ransom. The state government agreed to pay, but the children managed to escape and the kidnappers were subsequently jailed. One of them was called "Eastwood".

In real life, Andrew Robinson is a pacifist who despises guns. In the early days of principal photography, Robinson would flinch violently every time he fired. Producer and director Don Siegel was forced to shut down production for a while and sent Robinson to a school to learn to fire a gun convincingly. However, he still blinks noticeably when he shoots. Robinson was also squeamish about filming the scene where he verbally and physically abuses several schoolchildren, and the scene where he racially insults the man he pays to beat him up (Raymond Johnson).

In September 1981, a case occurred in Germany, under circumstances quite similar to the Barbara Jane Mackle case: A ten-year-old girl, Ursula Hermann, was buried alive in a box fitted with ventilation, lighting and sanitary systems to be held for ransom. The girl suffocated in her prison within forty-eight hours of her abduction because autumn leaves had clogged up the ventilation duct. Twenty seven years later, a couple was arrested and tried for kidnapping and murder on circumstantial evidence. According to the Daily Mail, the couple were inspired by the scene in which the Scorpio Killer kidnapped a girl and placed her in an underground box.

Before each of Harry's three combative encounters with the Scorpio Killer, there is a cross and or a reference to Christ: 1.) At the rooftop stakeout, the "Jesus Saves" neon sign. 2.) At the park ransom location, the giant, cement cross. 3.) And at around one hour and thirty-five minutes, at the pivotal moment when Harry is spotted by his nemesis from the school bus, a cross extending up from the streetlight. The Scorpio Killer even exclaims, "Jeeeesssus!" Additionally, in the scene where Harry confronts the Scorpio Killer on the field of Kezar Stadium, in one of the close-ups, perpendicular lines painted on the football field resemble a cross in one of the close-up shots of the Scorpio Killer whimpering in fear and pain.

For the iconic final shot when Dirty Harry tosses away his badge, Don Siegel was dismayed to discover that they had only brought one badge to the location shoot, so Clint Eastwood had to throw it perfectly in just one take.

Kezar Stadium, the scene in which Callahan shoots the Scorpio Killer, is the former home of the San Francisco 49ers, and has since been torn down and replaced with a smaller stadium for high schools. The field remained in the same place. The stadium is in Golden Gate Park.

Body count: seven (four kills by the Scorpio Killer, three by Harry assuming the pair of armed robbers he shoots died.)

The Hutchinson Company quarry, where the final shoot-out took place, was located just south of the Larkspur exit off of U.S. Highway 101. It was demolished in the mid 1980s.

This movie was Andrew Robinson's big screen debut.

In the final scene, when Harry asks "Did I shoot five or did I shoot six?", at that moment he had used five shots and had one round left in the chamber for the kill shot. It is incorrect to assume only four shots were fired, when in fact five shots were used before the final and fatal sixth shot. Four shots were fired inside the mill as Harry pursued the killer, the fifth shot was used outside the mill hitting the killer in the shoulder, allowing the child hostage to escape. The sixth shot was to the killer's chest, knocking him into the water.

When Harry is getting his leg looked at after being shot in the bank robbery scene he tells the Doctor not cut of his pant leg because they cost too much at $29.50. He is not joking As of 2021 pants bought in 1971 for that amount would cost over $200

Each of the Dirty Harry movies end the same way: With Harry Callahan walking off after dispatching the bad guy.

First of two Dirty Harry movies where a "Novena" was mentioned. In this movie, while making plans to leave a rooftop open to catch the Scorpio Killer (Andrew Robinson ), it was mentioned about having access to a Priest, who performs novenas. In The Enforcer (1976), after Harry (Clint Eastwood ) foils the plans of the heart attack victim to get free food, when he gets in the car, Inspector Frank De Giorgio (John Mitchum ) can be heard saying he promised his wife he would be home early for supper to attend a novena.

Dirty Harry fires a gun only 21 times throughout the entire movie. (22 if you include the '6 shots or only 5' empty shot at the beginning). 14 are with his 44 Magnum and the remaining 7 are with the rifle on the roof when trying to ensnare Scorpio.
