For those not satisfied with the level of detail on Rudd's beard, the trailer can be viewed in HD at Yahoo! Movies.

The cast on hand for My Idiot Brother is really impressive.  Rudd looks to be playing a refreshingly imbecilic variation on the nice guy routine that he has honed over the years, while Banks, Mortimer, and Deschanel are all actresses who can capably support entire films, so seeing them all together is quite a thing.  As if that weren't enough, though, the film also features comedic ringers like Steve Coogan, T.J. Miller, Rashida Jones, and Adam Scott. 

The film is directed by Jesse Peretz, who previously helmed five episodes of the Comedy Central series Important Things With Demetri Martin.
