Keanu Reeves is the worst of the lot... In the Matrix, while the rest of the cast were talking about colour-coded pills and non-existing spoons, Keanu's confused look throughout the movie was really genuine.... It wasn't until AFTER Matrix Revolutions did anyone actually explain what was going on, to Keanu... Best acting gig he ever did...
Then i would go for Liz Hurley... If it weren't for cleavage, she'd have nothing to go by... Not even her accent is cute...
Vin Diesel, well, he's an action star.. He doesn't actually NEED to act... All he has to do is LOOK tough, and know how to pronounce words... By that sense, Stallone couldn't act either, but he gets the job done... Sometimes, being "stiff" is a necessity for action stars...
Britney sucks, but one movie doesn't justify it... Mariah Carey is worse anyhow...
