According to Lea Thompson, she had a nude scene that was cut out of the final print. According to her, it was "too sexy" for the film.
The man who appears at the party scene claiming to be the father of Tom (played by Chris Penn) is portrayed by Penn's real-life father, Leo Penn.
In the scene where Tommy jumps out of the window, the music score by Eddie Van Halen is the exact same recording of the music used in "Back to the Future" when Marty puts the cassette in the Walkman to wake up George McFly.
The soundtrack was composed and recorded by Eddie Van Halen. Only three future Van Halen songs ever came from the music in the movie. One is "Good Enough" from the 1986 album "5150"; the second is "Right Now" from the 1991 album "For Unlawful Carnal Knowledge"; and the third is "Blood And Fire" which didn't appear until the album "A Different Kind a Of Truth" in 2012.
Nancy Wilson (from the rock group Heart, and writer Cameron Crowe's wife) appears as the wife of David the cop.
