Revealing mistake: In 1981, when most of the story takes place, the 1981 Dodge Diplomat was the most common police cruiser, but the director of this film chose the 1987 Chevy Caprice Classic.
Revealing mistake: This movie is set in the summer of 1981, however there is a scene where Val Kilmer is counting a whole bunch of 100 dollar bills that weren't printed until the mid 90's.
Chosen answer: 'If You Could Read My Mind' by Gordon Lightfoot.
