Here's a powerful film I'd recomend to any serious person: Frances.

It is the story of actress Frances Parker who was purported to have chronic mental illness, though were are never quite certain given the inexact science of the time (and now). Jessica Lange gives a chilling performance (as if she knew something of the subject). Triggers: hospitalization, sexual abuse, psycho surgery, manipulative parents.

Perhaps there is a little too much hollywood and not enough Frances in this film, but even if you enjoy it as a metaphoric period piece, this is an important movie to try and find.
