I figured all that celebrity casting would slow down as production kicks off, but Seth Rogen and Evan Goldberg are really packing things in during the home stretch. A few days after Rihanna was rumored to be in on the fun, THR informs us the duo’s directorial debut — now known as The End of the World — will also feature Jason Segel, Emma Watson, and David Krumholtz, all of whom are playing themselves.

Starring Rogen, Jay Baruchel, James Franco, Craig Robinson, Aziz Ansari, Jonah Hill, and Danny McBride — taking on slightly-altered versions of their real-life personas — The End of the World sees them hole up in Franco‘s apartment as the apocalypse starts waging itself outside. From that point, comedic antics take an expected, desired precedent. (I’d guess these three new members are also attending the party, though the specifics of how they come into it all doesn’t concern me; I just think it’s going to be a total blast.)

Side note: While prior associations with the creative team make Segel and Krumholtz‘s casting a little more obvious, Watson coming on was only made possible by a slight production delay on David Yates‘ Your Voice in My Head. This, therefore, is both a fair trade-off and the most interesting addition to an already-great lineup.

The End of the World opens on June 14th, 2013.

Is there now more promise for The End of the World?
