I need help finding a movie that talks about a mental disorder. It's for my homework assignment.

Hi ISABELLA. And i can help 你 in the aviator he has a mental disorder. And it gets worse as the movie goes. He has OCD, and some other mental disorders.

Hannible, Hannible Rising, and Red Dragon, hope this helps!

Sybil. It's about a girl who develops multiple personality disorder because of child abuse.

Of Mice Of Men. Its basicaly about two brothers and the youngest has downsyndrome (I cant really remember the 日期 it was set but we'll just say 'back then') uhm the younger brother is blamed for rape and can't comunicate properly to say any different. Its really sad but a good watch.

Hope this helped :)

Would Hamlet work? I mean, he did get pretty f*ckin' crazy.

Jersey shore.
Okay so it is a 显示 rather than a movie, and we don't know what exactly is wrong with those characters, but we all know something is wrong. XD

Any Asian horror movie lol.

Try A Tale Of Two Sisters; its about multiple personality disorder.

Girl, Interrupted
