^ What about The Scarlet Letter? Thats the only one I can think of where he plays the 'hero' sort of, its a romantic/tragic kind of movie. I personally loved it because of how adorable he/his character was (but the film did badly).
Also, theres State of Grace- his character is quite complex in this I don't think he's either evil/good. Its a good film thought, Ed Harris & Sean Penn are in it too & its one of Oldmans earlier films
Also, Rosencrantz & Guildenstern Are Dead! I think that would be a great movie to watch after seeing the clips on youtube. I think Rosencrantz is one of his best performances so far! However I've tried to buy it everywhere & have had no luck.
