Two classic films about psychiatric institutionalization and psychosurgery are "One Flew over the Cuckoo's Nest" (1975) and "Frances" (1982).

Parenthetically, I have yet to view a film with which I can identify as an accuately protrayed depiction of psychotic mania and excrutiating painful major depressive episodes endured by Bipolar I individuals like myself. Although I have seen a few woefully lame attempts in made-for-tv films.
