Trivia: The line "It's not who you go with, it's who takes you home" is said in every Prom Night movie, even despite the fact that the later films aren't true sequels to this one.
Prom Night (1980)
1 trivia entry
Directed by: Paul Lynch
Starring: Jamie Lee Curtis, Leslie Nielsen, Anne-Marie Martin, Casey Stevens
Revealing mistake: During the scene in which Lou forces himself on Kim in the lunchroom, donning a black ski mask, Kim's brother Alex jumps up to his sister's defense. Just before Alex throws his first punch, Kim screams "Michael," referring to the actor's real name Michael Tough. Kim then correctly screams "Alex," the name of the character he was playing in the film.
Alex: I know they did it, they killed her, they, killed her... Robin, Robin.
Answer: I don't believe so; there were clues that someone witnessed the murder. A shadow appeared before the dead girl. I believe Alex said a few words that hinted at that. I haven't seen the movie in years.
