Paul Rudd's Ridiculous Look For 'My Idiot Brother'

Paul Rudd knows how to make people laugh, but not because of his looks. He's an A-list cutie in that department, but while filming My Idiot Brother in NYC on Thursday, Paul took on a look we've never seen him sport before. Even co-star Janet Montgomery changed it up by embracing glasses.

Not only is he almost unrecognizable with his beard, mustache and long hair, but his clothes aren't too crisp either. The baggy sweatshirt and knit beanie don't do this lovable Hollywood hunk much justice.

Paul even looks a little healthier than usual, but we have a feeling that's just another part of his act! As unreal as his hot bod is off set, seeing him this way is just plain old idiotic!
