I have watched many of the movies listed above, but I go way back. My absolute favorite movie of all genres is the original The Day The Earth Stood Still. ("Gort. Crack yer knuckles burrito.") My favorite comedy is Father Goose with Carry Grant -- and I must not forget Carry Grant, Katherine Hepburn, and the pet leopard. I always forget the name but there is a very old B&W British comedy about a rich family and their butler who are marooned on a deserted Island. He becomes the leader of the castaways.
I like anything done by Ray Harryhausen. I like THX1138. I watched that one 12 times. I watched Twister 12 times. I watched The Exorcist 12 times. Sorcerer with Roy Schieder was intense. I like all the original Planet of the Apes. Old Charly Heston was pretty cool. Liked him in Ben Hur. Well, I've seen so many I can't remember them all.
