The names of the victims in the cast of characters are fictional and not the names of the actual victims of Ted Bundy.
Cameron Bright was offered a role but he and his mother did not want him to be associated with a serial killer.
In the scene when Ted and his girlfriend Lee are celebrating with friends at a party, a woman walks up to Lee introducing herself as "Beverly" and talks to her about working with Ted at a crisis center. Her character is clearly a reference to Ann Rule, a true-crime author who met and worked with the real Ted Bundy at a crisis center in Seattle, Washington during the early 1970s. Furthermore, Rule did, in fact, meet and talk with the real Ted Bundy's girlfriend at a Christmas party one year. Rule would later write a book about Bundy and his murders.
Photographs of the real Ted Bundy are featured in both the opening and closing credits of the film.
Rob Lowe, 'Peter Saarsgard', and Kiefer Sutherland were each offered the role of Ted Bundy. All of the actors refused due to the nature of the character. If Sutherland played Bundy, this would have been his second collaboration with Matthew Bright since Freeway (1996).
Jennifer Tisdale plays "Pretty Girl" who Ted follows down an alleyway. She is loosely based on Georgann Hawkins, who Bundy stalked down an alley. In real life, however, she vanished forever.
A scene where Ted Bundy takes one girl, fully conscious, into the woods, talks with her and then kills her befits the horror movie vibe this movie takes on Bundy. It's most likely, based on reports, evidence and Bundy's own confessions, his victims were unconscious when he strangled them (Bundy even bragged that he never "tortured" his victims). This is why Ted would leave nothing behind of himself to directly connected him to the murders i.e. there wouldn't be a struggle between him and his victim to leave parts of his skin in their nails, etc.
When Ted Bundy tells a woman that he's a police officer and her car's been broken into he then walks with her to her vehicle there's a sign on a building that says "Club Ted".
In the beginning of the film, Ted is shown stealing money from a woman's purse in a store. Bundy actually survived in Florida, towards the end of his serial killer reign, by stealing money this way.
Marina Black plays Kate, based on Carole Ann Boone, who was Ted's "other woman" who wound up marrying Ted after his arrest in Florida.
Katrina Miller plays Gilcrest, a 16-year-old cheerleader abducted outside a high school at night, and is based on Nancy Wilcox.
Rachael Rowan plays Bell, based on Caryn Campbell, who Ted Bundy abducted in a hotel corridor in Aspen, Colorado.
Ted Bundy is arrested trying to pick a car lock after he escapes in Aspen. In real life, he's arrested while driving a stolen car, not breaking into one. In fact, the three times Bundy was arrested was while he was driving, and for his inept skills as a driver. Also, in both this and the TV-movie The Deliberate Stranger, the female officer says the exact words, "Welcome back, Ted."
Young actress J-Ray plays Susan Bruster, who is based on Bundy's last victim, 12-year-old Kimberly Leach.
Tiffany Shepis plays Gabler, based on Carol DaRonch, the only of Ted Bundy's abduction victims who got away. Her testimony would lead to Ted's first arrest and incarceration.
Deborah Offner plays Beverly, from the Crisis Center who is based on author Ann Rule, Ted Bundy's friend, who both worked at the Suicide Prevention Crisis Center, and later the author of The Stranger Beside Me.
The stolen vehicle in Ted Bundy's arrest was a Volkswagen Bug in real-life as opposed to a van in the film.
The real Ted Bundy performed poorly in law school but graduated with honors in psychology; the film depicts Bundy as a poorly performing student in both psychology in law.
Ted Bundy's final arrest in 1978 took place in a residential neighborhood during the early hours of morning in real-life instead of an empty field in broad daylight, the latter of which was depicted in the film. While a chase occurred in both scenarios, the arresting police officer beat Bundy several times to incapacitated him in the film but fired a shot in real-life.
The execution chamber in the film has the electric chair's controls and the executioner (a female corrections officer) visible to the condemned and witnesses. In real-life, the electric chair's controls were in an adjoining room separated by a wall and curtained door while the executioner remains obscured from the witnesses and would be in the control room before the condemned was brought in and the before witnesses would take their seats.
Some of Bundy's real-life victims were condensed or combined into one character in the film. Examples of this include kidnapping victim Tina Gabler, who is based on Carol DaRonch and Rhonda Stapley, and cheerleader victim Jane Gilchrist, who is based on Nancy Wilcox and Debra Kent.
During the preparation of Ted Bundy's execution, his colon was packed with cotton and he wore a diaper to avoid soiling. At that time, the practice was discontinued.
Although the cheerleader victim Jane Gilchrist's death was based on Nancy Wilcox, it also mirrors Debra Kent, who was murdered when she was leaving her school's theater show to fetch her younger brother.
Kimberly Leach, Bundy's last victim, was returning to her school gymnasium to retriever her forgotten purse at the time Bundy abducted her. The film depicts Leach (renamed as Susan Bruester Moore) rope-skipping at a park.
The executioner depicted in the film is a hooded uniformed female corrections officer and is in plain view of the witnesses and the condemned in the death chamber. The Florida Department of Corrections watched the film and stated through a report that the executioner was a private citizen who was paid $150 and never wore a hood but was in the death chamber's control room obstructed from the view of both the condemned and witnesses.
Bundy wore the regular orange prison uniform during the film's execution. The real Bundy wore a blue death row uniform (with the right leg cut off).
Ted Bundy's last meal consisted of traditional steak (medium-rare), eggs (over easy), hash browns, toast, milk, coffee, juice, butter, and jelly. He didn't eat the meal and he also declined a special last meal.
Old Sparky, the electric chair used to execute Bundy, is depicted differently from the real chair in the Raiford Prison, where Bundy died.
Actual news footage of Ted Bundy's sentencing and the crowds gathering during his execution are shown in the film.
In Ted Bundy's first escape from prison, he exited from a window onto a roof and then jumped to the ground. The book "The Stranger Beside Me" makes a different account; Bundy jumped from the window to the ground, which happened in real-life.
The film shows Bundy losing interest in his studies after his girlfriend breaks up with him. In real-life, Bundy became more serious with his academics and worked harder to associate himself with American politics, ending up being a friend of Washington governor Daniel J. Evans and Washington State Republican Party chairman Ross Davis. This would later lead to his entry to law school.
Bundy's last words were "tell my family I love them". He actually said "Jim and Fred, I'd like you to give my love to my family and friends".
