There just isn't enough Zach Galifianakis for him to show up every time a fit leading man needs an overweight sidekick to squabble with. Thankfully, we have the very funny Patton Oswalt on-hand to pick up some of the slack. Oswalt, who hasn't really had a leading film role since 2009's perfectly-dark Big Fan, has signed on to star alongside Johnny Knoxville in writer/director Todd Rohal's upcoming "outlandish yet poignant" comedy about two feuding brothers who, in honor of their dying father, lead a group of boys on what becomes a disastrous camping trip. Step Brothers meets Darjeeling Limited meets Daddy Day Camp! Or something like that. Rob Riggle, Maura Tierney, and Patrice O'Neal will also star, providing their respective militant rage, affordable love interest, and racial diversity. Indie drama director-turned-raunchy comedy patron David Gordon Green will executive produce, and presumably fight for the film's freedom to get that comedy R-rating he's so fond of. God willing, no tent pitching joke shall be off limits.
