Blue Velvet is supposed to be a good Hopper film. Ain't seen it meself but will do at some point. He and Christopher Walken had a good scene together in True Romance.
Waterworld was crap because it was long boring and stupid... and Costner was probably trying to convey some preachy message about the environment, which is stupid since evreyone knows that the only way the sea levels will rise is if every toilet on earth was flushed at the same time.
Oh and for the Brits - Downfall (Der Untergang) is on C4 tonight.
