You know what would have been amazing? Seeing the bearded wonder, Zach Galifianakis, with the babely Ryan Reynolds in a comedy about zombie police officers. Right? Right? Well, unfortunately for us, Galifianakis is too busy to take part in what sounds like the coolest thing ever -- a flick called R.I.P.D. He was hoping to find time around the movie he's shooting with Will Ferrell and his obligation to the HBO show Bored to Death, but the studio just couldn't swing it. They're bound by Reynolds' schedule, which hinges on his role in the likely second installment of Green Lantern. So unfortunately we won't get the pleasure of seeing Marijuana Santa Claus and zombies. Grrrrr.
