Could the director of 2007's Best Picture favorite be tackling the horror genre next? Bloody-Disgusting is falling over itself today to report that one of it's top-secret spies on-hand at the Sundance Film Festival has learned that Paul Thomas Anderson is toying with a concept and will hopefully be making a decision on his next project in the coming months. Anderson's There Will Be Blood (which sounds like it should be a horror movie, but isn't) was announced this morning among the nominees for the Best Picture Oscar. Anderson's previous credits include Boogie Nights and Magnolia.
