The project is inspired by a short called Jay and Seth vs. the Apocalypse that featured Rogen and Jay Baruchel playing themselves, holed up in an apartment as they dealt with the end of the world.

Expanding upon the short, the story now includes not only Rogen and Baruchel but James Franco, Jonah Hill, Danny McBride and Craig Robinson, all playing themselves, as they are stuck in Franco’s Los Angeles apartment facing an apocalypse.

The script has fun with the actors, who might or might not make it out alive.

WME-repped Watson, best known for playing Hermione Granger in the Harry Potter movies, is in Los Angeles shooting Sofia Coppola’s The Bling Ring.

Segel and Krumholtz are longtime buddies of Rogen and Goldberg, going back to the early days when the latter duo came to Hollywood from Canada. Segel worked with Rogen (and with Baruchel) on the 2001 show Undeclared when he did a seven-episode stint. Krumholtz also appeared on the show as well as 1999’s Freaks and Geeks, which counted Rogen among its cast.
