During the parade several of the people seen dancing (including the construction worker and the window washer) originally had nothing to do with the film. They were simply dancing to the music being played and John Hughes found it so humorous that he told the camera operators to record it.

Cindy Pickett and Lyman Ward, who played Ferris' parents, married in real life after filming this movie.

To produce the desired drugged-out effect for his role as the drug addict in the police station, Charlie Sheen stayed awake for more than 48 hours before the scene was shot.

John Hughes told Ben Stein, who had a degree in Economics, to present an actual Economics lecture in his scenes. Hence nothing Stein says (aside from the roll call) is scripted.

Even though they played siblings, stars Matthew Broderick and Jennifer Grey would later become engaged after this movie. Tragically, approximately a year later, after Broderick finished filming Biloxi Blues, and before Grey's premier for Dirty Dancing, the couple was involved in a fatal crash in Ireland, where the passengers of the other vehicle, a mother and daughter, died in the accident.

The shot of Ferris playing the clarinet was done on the spot. Someone spotted the instrument as part of the set and Matthew Broderick said he could play it, which of course he couldn't.

The idea of a sequel had gone around for years with Ferris in college or on the job somewhere, but the idea was dropped. Matthew Broderick felt that the film didn't need a sequel, that this film was about a specific time and place that we'd all like to revisit and didn't need updating.

In 2010, Edie McClurg told "Vanity Fair" magazine that her character's hairdo should be from the 1960s, "because Grace felt she looked best in the [1960s] and kept her look from that era." However, the womens hairdresser on the set had mainly been hired to blow out Mia Sara's long, straight hair and didn't know how to set the big 1960s hairstyles--so McClurg teased, set and styled her own character's hair. Once she arrived on the set, John Hughes looked at her hairstyle and the first thing he said was, "How many pencils do you think you can fit in that hair?" They tested it with one pencil, then two and three, but the fourth one fell out--so that was the origin of Grace's first scene in the movie, in which she pulls several lost pencils out of her hair.

Grace the secretary pretending to be Ed Rooney during the phone call from Cameron was improvised.

John Hughes wrote the script in six days.

The hand that presses the speaker button on Cameron's phone belongs to John Hughes. When the crew left, Hughes took the camera and shot it himself since no one else was getting it right.

Alan Ruck was 29 years old when he played the role of teenager Cameron.

Cameron's father's Ferrari wasn't a real Ferrari. Because it was too expensive to rent one, three replicas were made--using an MG chassis--each with a fiberglass body.

Mia Sara says that Matthew Broderick actually tickled her feet and knees to get her to laugh naturally in the taxicab scene.

After working together on Weird Science (1985), John Hughes offered Bill Paxton the role of the garage attendant. However, Paxton turned it down because he felt the role was too small. He admits that he regrets turning it down because Hughes never offered him a role again.

According to the Inside Story (1986) documentary, Charlie Sheen's character's name is actually Garth Volbeck. There was going to be a whole back story to his character and family. It was also revealed that the Volbeck's was the family to whom Ferris' mom was showing the house for sale in her job as a realtor. If you look closely, the tow truck that towed Rooney's car was from Volbeck's Wrecking Service.

Mia Sara beat Molly Ringwald to the role of Sloane Peterson because--according to director John Hughes--she had elegance.

Whenever Mr. Rooney and Ferris have a conversation with each other, only one of them speaks throughout the entire conversation; the other is completely silent.

The painting that Cameron admires is called "Sunday Afternoon on the Island of La Grande Jatte", by Georges Seurat. It is still on display at the Art Institute of Chicago.

When Grace says "He's a righteous dude", it was not in the original script. Edie McClurg ad-libbed it in her best Chicago accent.

Rooney's line about leaving "my cheese in the wind" was ad-libbed. John Hughes wanted a comment that was complete nonsense.

Matthew Broderick improvised the scene and the line with the clarinet: "Never had ONE lesson!"

Rob Lowe, John Cusack, Jim Carrey, Johnny Depp, Tom Cruise, Robert Downey Jr. and Michael J. Fox were all considered for the role of Ferris Bueller.

John Hughes personally designed Ferris' bedroom, mirrored mostly on his own bedroom when he was in high school. Hughes said that the room was a disorganized series of pop references and other things because it would represent Ferris' mind.

The line Ferris says in the bathroom at the French restaurant about Cameron's house being very pretty and very cold was originally supposed to be said by Allison in The Breakfast Club (1985) regarding her home life.

Most of the license plates are all abbreviations for titles of films by John Hughes. Katie's = VCTN (National Lampoon's National Lampoon's Vacation (1983)); Jeannie's = TBC (The Breakfast Club (1985)); Tom's = MMOM (Mr. Mom (1983)); Rooney's = 4FBDO (Ferris Bueller's Day Off (1986)). The exception is Cameron's Ferrari (seen when Ferris first pulls out of the garage), the license plate of which reads NRVOUS.

The Ferris Bueller character was named after John Hughes' lifelong friend Bert Bueller.

Ferris laments not having his own car, but does at least own a synthesizer--which cost $8,000 in 1984.

Charlie Sheen was recommended by Jennifer Grey after they did Red Dawn (1984) together.

The outfit Ferris is wearing (hat, sunglasses and trench-coat) when he picks up Sloane from school can be seen on a mannequin in his room behind his door as his parents leave his room at the beginning of the movie to go to work.

The dance sequence by the group on the stairs during Ferris' lip-synch performance of "Twist and Shout" is taken directly out of Michael Jackson's Michael Jackson: Thriller (1983) video.

In the scene in which Sloane and Ed Rooney are standing outside, waiting for Mr. Peterson, the school in the background was John Hughes's old high school.

The 1961 Ferrari GT250 was a modified MG sports car. The producers received several angry letters from car enthusiasts who thought the car shown was a real Ferrari that was actually wrecked.

Polly Noonan, who plays the girl Rooney sits next to on the bus, wore glasses that were specially made by the prop department. The lenses distorted her vision so much that they made her nauseous. Also, the glasses were so heavy that she had to hold her head in a certain position to keep them from falling down.

The Parade sequence ("Twist and Shout" scene) was filmed during the Von Steuben Day Parade, an annual event in the Chicagoland area.

There is a poster for Simple Minds' song "Don't You Forget About Me" on Ferris' wall. This song was featured prominently in director John Hughes' earlier film The Breakfast Club (1985).

The hall scenes in which Jeanie is seen walking down the hall and the kid collecting money to save Ferris are the halls from The Breakfast Club (1985).

John Hughes refused to release a soundtrack album; he felt the mix of songs was too uneven and didn't flow together, and wouldn't work well as an album.

Deleted scenes: - Ferris asks his dad on the phone about bonds his father purchased when he was born, he then takes one of them from a shoebox in his father's closet, cashes it at the bank with his girlfriend (telling the hard-of-hearing teller they are pregnant with a jeep), and uses the money to pay for his day off. It was removed because it made Ferris look like a thief rather than a lovable rogue - Ferris orders something in French on the menu, and after everyone at the table tastes it, he is informed by the snooty waiter that he ordered "sweetbreads", which is a French dish made from the thymus gland. It was removed because it showed the waiter getting the better of Ferris, but later in the movie when Ferris is recounting the day to Cameron, he remarks "we ate pancreas".

When Ferris hacks into the school's computer to change the number of absences he had, it is a subtle reference to a scene in WarGames (1983) when Matthew Broderick hacks into the school's computer to change his grades.

The song "Danke Schoen" is heard four times in the movie; When Ferris sings it in the shower, when Ed Rooney sings it after ringing the Buellers' doorbell, when Ferris lip-syncs the Wayne Newton version during the parade, and when Jeanie sings it while walking down the stairs at the police station.

The shot of the street looking down from The Sears Tower was done by the second-unit crew. The camera person who operated the camera got sick because he had to be held over the side to get the shot.

The bus scene that plays during the ending credits was a scene cut from the movie. It was meant to take place after Jeanie announced that she called the police, and Rooney had to find a place to hide. This explains why the sky isn't dark, and why a bus is taking students home at 6:00 pm.

The short scene with the coughing keyboard was actually improvised by Matthew Broderick. This is explained in the commentary on the DVD.

The text that appears on the screen when Ferris is explaining how to fake being sick to his parents was added later because John Hughes thought the scene was too flat and not funny enough (according to him in the DVD Commentary).

In the film, Ferris and Cameron are supposed to be 18 years old and Sloane, 17. In reality, Matthew Broderick was 23, Alan Ruck was 29, and Mia Sara was 18.

A number of key moments in the movie were created in the editing room: Jeannie kicking Rooney three times in the face (when there was in fact only one kick filmed); Ferris and Sloane's kiss in front of Rooney was originally just a brief kiss, but was later edited into the long kiss seen on film.

The first edit of the film had a running time of 2 hours and 45 minutes.

During the scene where Rooney fights with the intercom at Ferris' house, there is a shot of the kitchen. On the refrigerator in that shot is a drawing of John Hughes, done by his son who was six at the time.

The final scene in the garage was shot in early fall, so each of the leaves on all the trees outside had to be hand-painted green every morning before shooting. In the shot looking up from the wreck at the three friends, the yellow tree with most of its upper leaves gone can be seen reflected in the window.

The Cubs game depicted in the movie that Ferris and his friends attend was an actual game played against the Atlanta Braves on June 5, 1985, based on research by Larry Granillo published in his Wezen-ball column at baseballprospectus.com on February 6, 2011.

The number "9" was chosen for the number of Ferris' absences because it sounded harsh when spoken by Rooney.

When the Ferrari crashed, the fiberglass hood ripped, but branches were put over the rip to make sure the camera didn't record it.

The French restaurant Bueller crashes is "Chez Quis", which is a pun, as said aloud it would be "Shakeys", the pizza chain. "Chez Qui" means "the house of whom" in French.

Anthony Michael Hall turned down the role of Cameron to avoid being typecast.

Cameron was based on someone John Hughes knew in high school.

This film takes place on June 5, 1985.

Ferris wears a different outfit in each scene before he and Cameron go to pick up Sloane.

In the scene where Sloane is sitting in the taxi with Ferris and Cameron in the floor, Ferris' dad is in a taxi next to them reading the newspaper. As the scene ends you can see the headline "Community Rallies Around Sick Youth", but the wording in the actual article indicates that it was about a Chicago policeman who killed himself.

The yellow and red insignia on Ferris' beret is that of the US Army's 32nd Armored Regiment; the motto at the bottom--illegible in the film--reads "Victory or Death". This was Elvis Presley's unit when he was in the army and in G.I. Blues (1960).

Early drafts had the Ferris family having younger siblings. When it came time to edit, the final draft actually has evidence that Ferris in fact does have younger siblings, such as drawings on the fridge and a family photo seen in his dad's office.

The two men in the funny hats who can be seen when Ferris and his friends are at The Sears Tower were in town on the day of shooting to watch the German Day parade that Ferris goes to later on.

John Candy auditioned for the role of Cameron Frye, but producers turned him down fearing he was too old for the part.

Emilio Estevez turned down the role of Cameron.

Ferris uses the word "finski" when referring to what he gave the parking lot attendant. "Finski" is regional dialect for a five-dollar bill.

The Ferrari was originally supposed to smash through the window of the garage and land in the backyard. It overshot its mark, however, and hit a fence that was dividing the house from the yard next door.

John Hughes personally selected the songs for the film. He wanted them to be somewhat obscure to the typical moviegoing audience, feeling that he wanted everything about the film to feel new.

Paul Gleason was considered for the role of Ed Rooney. Gleason had previously played the role of an assistant principal in The Breakfast Club (1985).

Despite the movie being set during the spring, this movie was really shot during the fall of 1985. There are several scenes in the film where you can see the trees are changing colors.

There is a theory circulating the internet that Ferris is just a figment of Cameron's mind. The theory states that although Cameron wants to be more adventurous and rebellious, he is afraid to, and so he creates Ferris. Ferris is all the things that Cameron is not. The theory also states that Ferris becomes a creation Cameron uses to finally assert himself against his father's cruelty and, more importantly, his own hypercritical conscience.

A scene that was filmed but never used involved Ferris going on a radio talk show and talking about being the first teenager to go into space. Bits of the scene were in the movie's trailer.

The school nurse who informs Sloane that her grandmother died is named Florence Sparrow, an obvious play on the name of the famous nurse, Florence Nightingale.

The brief scene of the valets driving the car to the Star Wars: Episode IV - A New Hope (1977) theme was done in post-production.

In an early draft of the script Ferris had two additional younger siblings and Jeanne was to be the middle child.

The woman playing the accordion on the parade float was a local named Vlasta Krsek. She gained a degree of notoriety from the film, even appearing on The Tonight Show Starring Johnny Carson (1962). On the show she played and sang the song "Twist and Shout", which was one of the songs from that famous scene.

Although one of the key scenes in the film has Ferris, Sloane and Cameron enjoying a Cubs game at Wrigley Field, John Hughes stated on the DVD commentary that he was not a Cubs fan. The scene was set there because of its iconic status and due to the Chicago White Sox rarely playing day games in 1985 during production.

The address of Ferris' house is the address that was on John Hughes' house when he was a kid.

In the scene where the kids are exploring the art museum, the music playing is an enhanced instrumental version of "Please Please Please Let Me Get What I Want" by The Smiths.

Ranked at #10 on "Entertainment Weekly"'s 50 Best High School Movies (2006).

The scene in which Ferris is drawing the nude woman on his computer was going to be broadcast onto a jumbotron in Chicago but the scene was later cut.

After the girl in the arcade spits her soda on Ed Rooney, a video game sound effect is heard in the background. Appropriately enough, it's the sound effect that denotes when a player has lost a life in the game Pac-Man.

Ben Stein, who plays the economics teacher in this movie, actually graduated from Columbia University in 1966 with honors in economics.

Shooting began in Chicago just after the Labor Day weekend, on Monday, September 9, 1985. In late October of 1985, the production would move to Los Angeles.

This entire movie takes place in one day with no flashbacks and most of the characters wear the same clothes throughout the whole movie.

When Ferris picks up Sloane from school, they are standing in front of the entrance to the theater of Glenbrook North High School in Northbrook, IL, director John Hughes' alma mater They then drive the car past the high school's soccer and baseball fields.

The house used as Cameron's home has four bedrooms, four bathrooms and is 4,000 square feet. It was designed in 1953 by A. James Speyer and David Haid.

Although Charlie Sheen used tricks such as sleep deprivation to look the part of his character 30 years ago, he did not feel it necessary to alter his appearance or personality to play the role in the recent The Goldbergs (2013)' homage to "Ferris Bueller" in the "Barry's Day Off" episode.

The scenes shot at Cameron's house began in September 1985 and finished in October of that year. The scene where the Ferrari was crashed was shot in mid-October. In order to have continuity and depict the garage scenes as the end of the school year, all of the leaves on the nearby trees were painted green. There is one scene after the Ferrari goes through the glass and the camera is down in the ravine looking up at the three actors standing in the garage looking down through the missing window. In the pane of glass next to them you can see reflections of distant trees which are yellow/orange as the fall colors were in full force by the time the scene was shot.

According to John Hughes in the DVD Commentary (original DVD release), the voice Cameron uses while talking to Rooney pretending to be Slone's father was modeled after a stage director both Alan Ruck and Matthew Broderick had worked for.

Charlie Sheen's role in this movie was filmed on one of his days off from the film Lucas (1986). His role came up mid-shoot.

Shermer High School is the same high school in Ferris Buellers Day Off, Breakfast Club, and Sixteen Candles.

Cameron is wearing a Gordie Howe Detroit Red Wings jersey. Howe was famous for playing professionally until he was in his early 50s, from 1946 until his retirement in 1980.

At one point in the film there was a line that Ferris was going to say about how "come next year, I'll be the first kid to ride on the Space Shuttle". It was even featured in the preview for theaters. However, less than five months before the film's release on January 28, 1986, the Challenger exploded 73 seconds after launch due to an O-ring failure in the right SRB, resulting in the deaths of all seven aboard, including New Hampshire school teacher Christa McAuliffe. Because of this, John Hughes had the preview recalled from theaters and the line was edited out of the final film.

Sloane was originally named "Tandy" in earlier drafts of the script.

During the downtown parade scene they pass a theater playing the movie "Godzilla 85". Matthew Broderick would go on to star in the movie Godzilla (1998) in 1998.

Sloane is named for Sloane Tanen, daughter of then-Paramount head Ned Tanen.

Mia Sara was a teenager during filming.

The name of the detective Ferris' mother talks to when picking up Jeanie is Stephen Lim (the name can be seen on door when mother exits office.) This is also the name of First Assistant Director Stephen Lim,

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

A theory arose that Ferris doesn't actually exist and he is just a more outgoing, brave alter-ego of Cameron that he made up to deal with his father. This begs the question: Was the whole day just Cameron day dreaming in his bed while sick?

"The Ferrari in the movie was a replica of a Ferrari 250GT California Spyder (only 104 of which were actually produced). This version of Ferrari's already famous 250 series was designed specifically for the American market, featuring only two seats, a convertible top and more horsepower than in the standard European version.

In Ferris' bedroom there is a poster for 'Don't You (Forget About Me)' by Simple Minds, the same song used in the beginning and the end of one of John Hughes' previous films, The Breakfast Club (1985).

The passage that Ed Rooney quotes when he is trying to console Sloane ("man that is born of woman hath but a short time to live...") is the "First Anthem" for the Burial of the Dead from the Book of Common Prayer produced by the Anglican church. The anthem is based on Job 14:1-2.

Cameron Frye's birth-date is 1 July 1967. Alan Ruck's birth-date is 1 July 1956.

Ferris's sampler/synthesizer is an E-MU Emulator II.

The car parked to the left of the Ferrari in the garage is an MG J2 (the Ferrari is actually a fiberglass body of a Ferrari on an MG chassis).

Originally, the Modigliani that Ferris is tinkering with on his computer was wired to a Jumbotron downtown.

In the scene where Ed Rooney is at Ferris' house, before he rings the doorbell he is humming the same song that Ferris sings in the shower at the beginning of the movie.

Director John Hughes didn't like Ferris' beret when he is driving the Ferrari, but he really liked Cameron's flat cap.

Tom Skerritt was considered for the role of Ed Rooney.

Cameron wearing a Detroit Red Wings hockey jersey is actually an insight to his character. For the last 20 years or so, the Red Wings have been a top team in the NHL. However, back during the time this film was made, the Red Wings were the worst in the league with an embarrassing win/loss record. Cameron wore a Red Wings jersey to show that not only is the character "a lovable loser down on his luck" but that even the team he supports are losers. The Red Wings have also been long time rivals to the Chicago Blackhawks.

Kristy Swanson was originally cast in the small role of the girl who talks on the phone with Ferris in the school hall. However, the role was re-cast with Kristin Graziano because John Hughes felt it was better to film the scene in Chicago. Hughes had liked Swanson so much,l though, that he offered her the part of the Economics student, which was shot in Los Angeles.

Louie Anderson had a small role as a flower deliveryman in this film. One of the episodes of his 1995 television show, Life with Louie (1995) was titled "Pains, Grains and Allergy Shots," a reference to the John Hughes film Planes, Trains & Automobiles (1987). Anderson's TV show also featured the voice talents of Edie McClurg, who is notable for appearing in many of Hughes' films, including this one.

Eric Stoltz auditioned for the role of Ferris.

Ferris has a Cabaret Voltaire "Micro-Phonies" poster to the left side of his door.

The bus scene at the end of the movie where Dean Rooney is picked up was shot in Long Beach, California, at Los Cerritos Park.

The high school band playing in front of the float Ferris is on is a real high school band from Lockport Township High School, a small town just south of Chicago.

During the scene at the Sears tower, Ferris says it's the World's Tallest Building

At the time of filming, the Sears tower was NOT the tallest building in the World, that title went to the CN tower in Toronto Canada.

The poster behind Ferris Bueller's bed is of Bryan Ferry.

When the trio is back at Cameron's house, attempting to push the mileage back, nearly four minutes pass between Ferris saying,"We'll have to break the glass on the odometer and roll it back by hand" and after the Ferrari speeds through the glass to the foliage down below when Ferris says "You killed the car." During Cameron's rant about his problems with his father, neither Sloane nor Ferris say anything or make any sort of noise. Neither makes a sound, such as a scream, even when the car goes out of the window.

The detective's name is Steven Lim. The film's first assistant director is also named Stephen Lim.

The license plate says on the red Ferrari NRVOUS.

Cameron wears Gordie Howe's Red Wing jersey #9, which is also the number of days Ferris has already skipped school.

There are two region-specific items of clothing in the film. The Detroit Red Wings jersey and a letter jacket. The letter jacket is from a school in suburban Detroit - Birmingham Groves High School.

Apparently it is just not Ferris and his pals that skip school. Two girls who look the same age as Ferris are seen playing an arcade game at a restaurant. If you look carefully during the baseball match a blonde haired boy who looks no more than 8 years old is behind Ferris and his pals.

Matthew Broderick has also played a young whiz kid in the film WarGames (1983).

John Hughes: can be seen in a tiny cameo in one of the early Chicago downtown montage sequences, climbing literally across traffic, from right to left of screen, wearing a light blue jacket and big "'80s hairdo" (from DVD director's commentary.)

John Hughes: [The Beatles] Ferris lip-syncs The Beatles' cover of "Twist and Shout". He quotes John Lennon's song "God" ("I don't believe in Beatles, I just believe in me.") Cameron's Detroit Red Wings jersey references Paul McCartney and Wings, as his Epiphone Texan acoustic guitar (which he played on The Beatles' "Yesterday") sported a Detroit Red Wings sticker from the mid-1970s onward.

John Hughes: [Shermer] When Jeannie is in the police station, you see a quick shot of the chest of a police officer including his badge which identifies him as a Police Officer in the town of Shermer.

John Hughes: [eyes] close-up of eyes widening in horror.
