Seth Rogan and Evan Goldberg have written a script (along with Kyle Hunter and Ariel Shaffir) called Sausage Party. Conrad Vernon and Greg Tiernan will direct the film, which will be animated and totally R-rated. The plot has something to do with a hunk of meat falling out of a shopping cart and discovering "the truth about its existence," which doesn't sound very nice.
The film itself should sound nice thanks to its really funny voice cast. Seth Rogan, James Franco, Michael Cera, Jonah Hill, Edward Norton, Nick Kroll, and David Krumholtz are all involved. Kristen Wiig also has a part but only because she auditioned in overalls and a fake mustache. By the time they realized she wasn't a dude it was too late.
This is an Annapurna joint, by the way. With this cast and those screenwriters, this has ever chance of being hilarious. But it will also have heart. We will likely all walk out of the theater vegetarians. For a day or two.
