I'm fairly certain that Paul Rudd is a smart guy, but he certainly know how to look dumb. Just by putting on a goofy smile he can make his IQ level appear 50 points below what it actually is. Naturally, that's promotional gold for a movie called Our Idiot Brother.

Moviefone has posted the first poster for the film and while it's a fairly simple design, it's quite effective. A pointillist design, the one-sheet looks like it could have been torn out of the back pages of an old comic book, and there, in the middle of a yellow stamp, is our wonderfully idiotic protagonist. I can't wait until this movie finally arrives on August 26.

Check out the poster below.
