Watson, Cera, Segel, and Rihanna joining Rogen’s Apocalypse party

Even more stars have joined Seth Rogen and Evan Goldberg’s directorial debut/end-of-days party, The Apocalypse.

According to The Hollywood Reporter, Harry Potter‘s Emma Watson is in negotiations to appear in the flick.

Rogen previously revealed that Harry himself, Daniel Radcliffe, turned down an opportunity to star, stating, “it doesn’t look like he’s willing to push things as far as we are.”

Former collaborators Jason Segel and David Krumholtz are also set to join the cast.

Variety, meanwhile, revealed Michael Cera is circling the project, while Rihanna is likely to sign up as well.

Already attached to the flick: Jonah Hill, Danny McBride, Aziz Ansari, Craig Robinson, James Franco, and Jay Baruchel.

All actors will be playing themselves, hanging out at Franco’s pad when the world ends.
