McGregor had nothing to do with the failure of The Island. The fact that it was a horribly written movie directed by the king of horrible teen summer movies is what made it a failure. I mean, they really tell you EVERYTHING about the story in the trailers. There was nothing surprising about the movie at all.

Besides, if I want to watch a movie about a dystopian future where there is a character running from something, I'd rather watch Logan's Run or THX-1138.

Though, I have to admit... Ewan's acting didn't seem as good in this movie as it normally does. I wish he'd do something with Boyle again...
