American feature animation just got a little more adult. Sony Pictures will release its first R-rated animated film in 2015. The CG pic, Sausage Party, is being written by actor Seth Rogen, along with Evan Goldberg, Kyle Hunter and Ariel Shaffir. This will become the first wide-release R-rated US animated feature since the 2007 movie based on Adult Swim’s Aqua Teen Hunger Force.

Sausage Party will be helmed by Conrad Vernon, the co-director of Shrek 2, Madagascar 3 and Monsters vs Aliens, and Greg Tiernan, the director of the TV series Thomas the Tank Engine & Friends. Nitrogen Studios Canada in Vancouver will handle the animation production.

The film, which is being described by its producers as “raunchy,” will star a sausage on a quest to discover the truth about his existence:

After falling out of a shopping cart, the hero sausage and his new friends embark on a journey through the supermarket to get back to their aisles before the 4th of July sale.

Co-financing on the film is being provided by Annapurna Pictures, the production company run by Megan Ellison, the daughter of billionaire Larry Ellison.
