How Could you forget the best movie of all time. Carrie
Conspiracy theory ranks high
I liked beautiful mind
Mommie dearest
Girl interrupted

Girl, Interrupted
A Beautiful Mind
It's really old and I believe its only in black and white...Marnie with Tippi Hedren and Sean Connery

I don't think marnie had a mental disorder, she just had repressed memories from a childhood trauma.

If you like Girl, Interrupted you should love One Flew Over the Cuckoo's Nest, with Jack Nicholson. Great movie.

Sean Penn- I am Sam- Sean was brilliant in this movie. Oscar worthy performance.

The Hand that Rocks The Cradle- (black gardener)

Russel Crow -A Beautiful Mind

Leonardo DiCaprio- The Aviator (Howard Hughes suffered with obsessive compulsive disorder and reclusiveness)

Jane Eyre

Girl Interrupted

Jolie deserved an Oscar for that role. And Brittany Murphy was spectacular (RIP) we lost a great actress in her...

I like a lot of movies on that list, but I haven't seen them all. The movie "Identity" also deals with dissociative identity disorder. It's pretty good!
