Seth Rogen and longtime bud and collaborator Jay Baruchel are gearing up to shoot their post-apocalyptic horror-comedy Jay and Seth Vs. The Apocalypse, which will center on two friends who grow increasingly irritated with each other in the claustrophobic end-of-the-world atmosphere. The project has been laboring in development for a while now, but the boys are finally set to roll this February, and Rogen has told MTV (via /Film) that more of the Apatow Mafia will join them, saying, “We’ve decided to add more people, so ideally ‘Jay and Seth’ looks like it has become Jay [Baruchel], Seth [Rogen], Jonah [Hill], Danny [McBride], Craig [Robinson] and James [Franco].”

There have been a lot of rumors about who else may be featured. As Rogen has said the flick would take place in a decimated Los Angeles, he is hoping to score a bevy of cameos, “I want a lot of dead celebrity cameos. Because L.A. is full of famous people, I’d like all of the cameos to be them as corpses.” Rogen has also revealed he and the his Pineapple Express/Knocked Up co-stars will be playing themselves, so expect a lampooning of Los Angeles and celebratory culture along with some yet to be revealed cameos. However, the script’s crude and inflammatory tone has already scared off some celebs, including Daniel Radcliffe, who Rogen admits wasn’t, “willing to push things as far as we [are].”

Considering Radcliffe seemed game to poke fun at his good boy persona on Ricky Gervais’ biting insider comedy series Extras and fearlessly performed on Broadway nude in Equus, I’m undeniably curious to see what goes outside of Radcliffe’s comfort zone. We’ll give you more cast updates as we get them, but in the meantime you can view this early fund-raising trailer for Jay and Seth Vs. The Apocalypse here:

 Who else would you like to see join Jay and Seth? Am I the only one hoping for Charlyne Yi to pop up?
