James Stewart (1908-1997) is my all-time favourite actor (though in regards to his politics I generally differ). Anywhoo, I mention this because I was pleasantly surprised to find a recent article on James Stewart on CNN. From the movies I've seen, and what I've read, I greatly admire Stewart as both actor and person.
You can find his filmography here. He's made some great movies, and some not-so-great movies, but I enjoyed watching all of them. Well, to be perfectly clear, I did think a couple of the movies were pretty poor--but Stewart's presence made those particular films bearable ;o)
