Harvey. Yep, the old black and white one with James Stewart.
Time Bandits
I'm not sure if it is my favorite movie of all time, but it's one of my favorites and I can watch it any time of year regardless of what mood I'm in.
Favorite horror is a tossup between The Thing (dir. John Carpenter) and Invasion of the Body Snatchers (feat. Donald Sutherland and Leonard Nimoy).
Mystery Men. It's a parody of superhero/comic book movies. Ben Stiller as Mr Furious, Janeane Garofalo as the Bowler, William H. Macy as the Shoveler, Hank Azaria as the Blue Raja, Greg Kinnear as Captain Amazing, Tom Waits as Dr. Heller, Paul Rubens as the Spleen, Wes Studi as the Sphynx.
Monty Python and the Holy Grail...Life of Brian...High Plains Drifter...Sergeant York...parts of Throw Mama from the Train...parts of It's a Wonderful Life...If I'm watching nothing in particular and scan the channels and find one of these movies, I will stay and watch it to the end, even if it makes me late for something else...
