Mutt-and-Jeff comedies are always a little funnier, I think, when the characters are older than usual unless, of course, they’re playing serious dumbasses, in which case it’s not as funny as it could or should be. But what works, I think, is when one of the characters is in the grip of genuine self-loathing, and yet the kind of self-loathing that’s been pushed so far down that he’s not even aware that it’s there. Jason Bateman and Billy Crudup appear to be in their mid 40s or thereabouts. In ten years we’re going to see comedies about guys in their 50s still trying to grow up and act like adults.
