I'll add a recommendation for The King's Speech. Also Red with Helen Mirren and Bruce Willis. Have you seen The Queen with Helen Mirren? I thought that one was good. Anything with Peter O'Toole such as The Lion in Winter and Becket.
Then, there's always Mr. Roberts (one of my all time favorites.) Some of the Harry Potter movies are good; others (like the last one) not so hot. Watch them in order. Anyone seen the latest Harry Potter?
