Well, this is one way to get out of diaper duty: Ben Affleck is set to star opposite Jeremy Piven, Ryan Reynolds and Alicia Keys in Smokin' Aces, a feature about a Vegas magician (Entourage's Piven) marked for murder. "You'll be shocked to see a very different Ben Affleck in this movie," Reynolds tells the Chicago Sun-Times. Which I think means that Matt Damon will be playing him.
