One of the guys in the line-up (which takes place in Colorado) is played by the same guy who also played one of the anonymous "Teds" being interrogated by the Seattle police.
In the beginning of the film, Ted murders his first victim, Ann Pitney (based on Georgeann Hawkins). It's shown with Bundy sneaking up behind the victim (while she was walking down a dark alley from her boyfriend's dormitory) and snatching her. In reality Bundy first approached Hawkins while he was on crutches and carrying a briefcase (he often feigned injuries to ensnare his victims), and asked Hawkins to help him carry it to his car (which was nearby). He lured her into a secluded parking lot near the alley. Bundy then unlocked his car and opened the door, and as Hawkins bent over to put his books into the car he grabbed a crowbar he had hidden under the wheel of his car and knocked Hawkins out cold. However, at the time the film was made, Bundy had not confessed or given the details to Hawkins murder, so the exact details of her death where not known at this time. It wasn't until three years after production, days before his execution, which Bundy confessed to Hawkins murder.
Emily Holds (based on Melissa Smith) is portrayed as a teenaged runway seen hitchhiking a ride on the highway and getting picked up by Ted. In reality, Melissa Smith was abducted by Bundy as she left a local pizza parlor (in her small town) to run home and get clothes for a sleep over (which she never made it to). Smith was not running away.
Ted Bundy is shown to be captured in a suburban area in Lake City, Florida; the real-life Ted Bundy was captured outside Oscar's Restaurant in Pensacola, Florida.
Katie Hargreaves (based on Laura Aime) leaves a Halloween party dressed in a Greek God Halloween costume. According to Kevin M. Sullivan's book 'The Bundy Murders: A Comprehensive History', Laura Amie was last seen wearing blue jeans, a sweater, and a hooded jacket that bore resemblance to a navy pea coat.
Katie Hargreaves (based on Laura Aime) is seen leaving a Halloween house party mildly intoxicated to buy a pack of cigarettes. In reality, Laura Amie left a Halloween party but it was at a local cafe (not a friends house). Amie was also not as intoxicated as she was portrayed to be in the film at the time of her disappearance. Amie also left the party because she was bored with the activity. Some sources also indicate that Amie was indeed leaving to buy a pack of cigarettes, others state she was heading to a local park, while others say that she was heading home, but her exact destination has never been confirmed.
Several cars from the 1980's are shown in parking lots and on streets during the 1970's portion of the story.
The Utah mall incident occurred in 1974 yet the Stevie Nicks album "Rock a Little", which is displayed on the store window behind Bundy and his intended victim, was not released till 1985.
The Theater at the Utah Mall has "Out of Africa" as one of the films playing. This incident took place in 1974 and "Out Of Africa" didn't hit the big screens until 1985.
In a scene where Cas is supposedly reading an article about the Ted murder case, the actual article under the headline has nothing to do with the story. In fact, it is nothing more than three or four paragraphs reprinted next to each other to look like a real newspaper article. This can be verified when the DVD is paused when a close up shot of the headline is shown.
