Another entry in the filthy-comedy genre, co-written, co-directed, and starring Seth Rogen. It's funny, unless you are offended by unremitting comic references to substance abuse, discussion and depiction of unusual sexual practices, an avalanche of dirty words, blasphemy, cannibalism, etc. (MPAA: "crude and sexual content throughout, brief graphic nudity, pervasive language, drug use and some violence")
The gimmick is that most of the actors play themselves. Although—geez, I hope—heavily fictionized versions of themselves. Because they are portrayed as uniformly stupid, vain, gluttonous jerks. In addition to Rogen, we got: James Franco, Jonah Hill, Jay Baruchel, Danny McBride, and Craig Robinson. Smaller roles are inhabited by Michael Cera, Emma Watson, Mindy Kaling, David Krumholtz, Christopher Mintz-Plasse, Rihanna, Martin Starr, Paul Rudd, and Channing Tatum.
OK, so I don't know who some of those people are either.
But most of them show up for a big party at James Franco's
house. Unfortunately, the party is scheduled for the same
evening as the Apocalypse, which rapidly lays waste to
most of the Greater Los Angeles area. Yawning
pits of hellfire are opened. Ravenous supernatural beasts
roam the streets. Inanimate objects turn deadly.
<spoiler>Jonah Hill gets
<spoiler>. And the very flawed
actors start re-enacting Lord of the Flies for real,
as their thinner-than-normal veneer of civilized behavior
Some neat special effects. I stayed awake and laughed a lot throughout.
