Here's two trippy films worth watching...

"Eternal Sunshine of the Spotless Mind" - Jim Carey and Kate Winslet. Directed by Michel Gondry.

"Confessions of a Dangerous Mind" - Sam Rockwell & George Clooney. Directed by George Clooney. I must say, it's a pity Clooney doesn't abandon his acting career and pursue directing full time because he's much better behind the camera than he is in front of it.
