Memento - This is a murder mystery told backwards. Demanding but fascinating, IMO. You'll either watch it a few times to grasp all of the detail(me) of give up after 15 minutes(my wife).

Killer Clowns from Outer Space - The title says it all. Great horror fare for those of us who always suspected that clowns are evil.

Stranger than Paradise - By director Jim Jarmusch, who later directed Sling Blade. This was one of his first. I thought it was hilarious. It's not really about much of anything... definitely an acquired taste.
