Not a genre I waste much time on -- I prefer to be entertained -- but The Luzhin Defence was pretty good.
Live broadcasts of debate in Congress / Parliament
Since Hippy got the one I was thinking of, how about: Whatever Happened to Baby Jane?
Awakenings with Robert De Niro and Robin Williams.
Another good one was on just today, Psycho.
One Flew Over the Cuckoos Nest. Classic Jack.
Saw. Chucky (whatever ones). Friday the 13th. But I can't really watch them.
