Which actor played the leading role in the film "The Butterfly Effect"?

ZyggyStardust, sounds interesting!

Bezimak They need to give credit that the title and concept comes from an old sci fi short story in which a time traveling tourist to the dinosaur age steps off the path and kills a butterfly. Upon return to present, much is changed. Return visits to correct follow... The Simpson's even had a short based on it in one of their Halloween specials.
