St. Elmo's Fire (1985)

Continuity mistake: In the bar scene when Billy is playing the saxophone on stage, his wife enters the bar with her boyfriend. The saxophone music keeps playing after Billy starts glaring at them, even though Billy has stopped blowing air into the horn and is not pushing the horn's buttons.

Audio problem: When Wendy and Jules are talking in the bathroom, two women walk by and say "Hi Leslie" and "Hi Les, how ya doing?" to Leslie. It is easy to see that their mouths do not move in sync with the words that are heard.

Continuity mistake: In the scene where Demi Moore drives Rob Lowe home in her jeep, Demi is wearing white, long earrings. When she tuns to talk to Rob Lowe she has both on them on. When they cut to him and then go back to her she only has one on. Then, again they cut back to Rob Lowe and then back to Demi, she has both of them on again.

Trivia: Mare Winningham, whose storyline revolves around the fact that she's a virgin, was pregnant throughout the filming of the movie. This is the reason she's wearing those baggy clothes.

Trivia: Ally Sheedy was mortified after learning that she had to perform a sex scene as she presumed that it would be offscreen and simply implied. Director Joel Schumacher convinced her to do it by agreeing to only shoot her and Andrew McCarthy from the neck up. Also the scene where she accidentally pushes the shower screen down was unscripted and McCarthy's laughing reaction was genuine.

Kevin: Oh, did you move in too? I just remember 200 pairs of shoes.
