Shawshank Redemption. Arguably, the greatest movie ever made.
Chronicles of Riddick
Many more I can't think of right now..but those are a definite "flip-to" if I see them playing.
And one, very obscure movie, that will probably never be shown on TV again, as it is from the late 90's and had no major theater release..
The Mating Habits of the Earthbound Human. It's a mockumentary, narrated by David Hyde Pierce. It's tough to find, but I got a copy on Amazon, DVD only for $15.. I wanted BluRay, but it's not available in that format. Not a requirement effects wise, but if you can find it, watch it. You will laugh, a lot. or you may be dead.
