Whenever I think of Obsessive-Compulsive Disorder in terms of movies, Jack Nicholson comes to mind and his rendition of Melvin Udall in As Good As It Gets. He seems to have his performance down of this pattern-prone anxious man, and is the vision of what happens when you get between the poor sufferers of this disorder and the pattern they feel they must keep to in order to remain calm. The man makes you cringe when he throws a hissy fit, but makes it funny, too.
