Continuity mistake: In the scene where Sam is doing his Buster Keaton act, his tie is done up. When he jumps in his hat it's down, then when Benny is helping him up it's back up again.

Benny & Joon (1993)
Plot summary
Directed by: Jeremiah S. Chechik
Starring: Johnny Depp, Julianne Moore, Aidan Quinn, Mary Stuart Masterson
Benny (Aidan Quinn) is a mechanic who has been taking care of his mentally ill younger sister, Joon, since their parents died. This consumes his whole life, and gets in the way of a relationship he is pursuing with a pretty actress-turned-waitress, Ruthie (Julianne Moore). When Joon loses in a poker game, Benny is forced to take in his friend's eccentric cousin, Sam (Johnny Depp), a loner who loves movies, especially silent ones. Everything is going well, until Sam and Joon start a relationship, which Benny violently dissaproves of.

Joon: Don't underestimate the mentally ill. We know how to count.
Question: What exactly is wrong with Joon? I don't think they mentioned it in the movie, but does anyone have a good guess?
Answer: Initially, I thought that she had PTSD after her parents died because she appeared to have watched the accident or been in the accident.
Answer: She had schizophrenia, she showed that with her paranoia when she accused Benny of cheating and hallucinations when she was getting upset with the voices in her head on the bus.





Answer: I would guess high functioning autistic. Similar to Rainman. Especially her being obsessive compulsive.
