The Butterfly Effect
 

I saw the preview for this at "Return of the King" and it looks pretty decent. It stars Ashton Kutcher as this guy that goes back in time to save his girlfriend and ends up changing everything, like Jeff Goldblum talked about in "Jurassic Park". ;)

Here's the trailer: http://www.apple.com/trailers/newlin...terfly_effect/

I can see it now...
"OMG I HATE ASHTON KUTCHER, THIS MOVIE WILL SUCK!!!"

Actually I thought the movie looked pretty good :) .
