What's Your Favorite Dennis Hopper Movie?

"And am I gonna be the one that's gonna set them straight? Look at me! Look at me! Wrong!"

Dennis Hopper was one of those actors who didn't seem to be happy unless he was shocking his audience, or at least setting their teeth on edge.  Hopper's back story is much more involved than I'd appreciated until I listened to Terry Gross' past interviews with him on Fresh Air the other day.  As for favorite movies featuring Hopper, mine is Apocalypse Now, of course, with Easy Rider running a close second.
