Adam McKay’s comedy “Step Brothers” opens July 25, 2008, which means it’s about time to release some more promotional material for the film. Just a couple of days after premiering an exclusive clip from the upcoming flick starring Will Ferrell and John C. Reilly, Yahoo! Movies now added four more clips.

As you can see below, these short clips are merely extensions of some scenes we’ve already seen in the trailer. The plot centers on two spoiled adults who involuntarily become highly competitive stepbrothers. Enjoy!
