When we first reported on Sony Pictures' Sausage Party back in September, it wasn't immediately clear if co-writers Seth Rogen and Jonah Hill will also have voice roles in the R-rated animated comedy. Today, we have confirmation that both actors will be a part of the voice cast, along with their This Is the End co-stars James Franco, Michael Cera and David Krumholtz, with Kristen Wiig, Edward Norton and Nick Kroll also signing on for voice roles.

The story follows a sausage who falls out of his shopping cart, and goes on a journey with some new friends through the supermarket to find his way back home before the dreaded 4th of July sale. Back in October, co-writer Evan Goldberg revealed that the film is an "existential mock-Pixar movie," which attempts to take Pixar "down a notch," despite how much he loves their movies.

No details were given for which characters these voice actors will play. Conrad Vernon (Madagascar 3: Europe's Most Wanted) and Greg Tiernan are directing from a script written by Seth Rogen, Evan Goldberg, Kyle Hunter and Ariel Shaffir, based on a story by Seth Rogen, Evan Goldberg and Jonah Hill. Megan Ellison is producing through her Annapurna Pictures company, with James Weaver, Jonah Hill, Kyle Hunter and Ariel Shaffir executive producing.
