I vaguely remember this old one, "David and Lisa", probably goes back to the 50's, I just remember no one could ever touch David, he had some disorder where he'd freak, and I can't remember what Lisa's thing was, I was only a little kid.
Then there was one called "Autumn Leaves" probably from the early 60's or late 50's too, I think it was based on a writer who had had a breakdown.
I vaguely remember them, but remember my parents watching any movies then about mental illness, when my brother had his first breakdown, back in the very early 60's, and was DXed with "manic-depression" now referred to as "bipolar",
I guess cause it sounded better.
Maybe "google" can give us more info on those old but good movies,eh?
