In The Incredible Burt Wonderstone, Steve Carell played a Vegas magician and James Gandolfini played a casino owner. As Deadline reports, in their next project together, they'll take the logical step forward and play paleontologists. Titled Bone Wars, the HBO movie will tell the true story of the famous post–Civil War fossil feud between Edward Drinker Cope of the Academy of Natural Sciences in Philadelphia and Othniel Charles Marsh of the Peabody Museum of Natural History at Yale. Their rivalry lead to the discovery of more than 160 dinosaurs and each man's personal downfall. The comedy is still looking for a writer and director. Is Ross Gellar busy?
