I wasn't able to see the movie completely on TV since I was playing billiards at the same time but from the little that I saw it reminded me a lot of one of my favourite movies: "David and Lisa". It has a lot more to do with that movie than the other ones mentioned here. Even the main actor resembles a lot the one in that movie Keir Dullea. The billiards was a bit like the chess game on the David and Lisa movie. I think both movies stress the importance of human relations more than institutional help and I found that the David and Lisa movie was a bit revolutionary by showing that mental institutions aren't evil places like the one shown in One Flew Over .... The psychiatrist on this movie does remind me a lot of the one in David and Lisa. Another related movie is the David and Lisa version done by Oprah Winfrey with Sidney Poitier. Of the three I still prefer by far the first one.
