Hilarious! Horrifying! Unbelievable! It's finally here. Watch if you dare, this sneak peek is truly terrifying for vegans and meat lovers, both. Sausage Party is the ever first R-rated CG animated movie. It is about one sausage leading a group of supermarket products on a quest to discover the truth about their existence. And what really happens when they become chosen to leave the grocery store.

This Pixar spoof is from writers/producers Seth Rogen and Evan Goldberg, and while it might look like it's headed for an NC-17 rating, the creators assured advanced audiences last night at SXSW that it has already been awarded an R rating by the MPAA. It is directed by Greg Tiernan and Conrad Vernon. And it is definitely not for children, so keep them far, far away.

Seth Rogen headlines this adventure as a hotdog just looking to get laid inside a delicious bun. But he soon discovers his destiny lies upon a different path. The film features the vocal talents of a who's who of today's comedy stars. The ensemble also includes Kristen Wiig, Jonah Hill, Bill Hader, Michael Cera, James Franco, Danny McBride, Craig Robinson, Paul Rudd, Nick Kroll, David Krumholtz, Edward Norton, and Salma Hayek. Here's what co-director Evan Goldberg had to tell us about the movie.

"Sausage Party is an existential mock-Pixar movie, and we are very, very proud of it. It's our opus. It's like Mr. Holland's Opus! It's our take on a Pixar movie. It is very, very R rated. I wish there were fifty Pixar movies every year. But listen, someone should take those motherf*ckers down a notch. Those high and mighty bastards. We're mocking all animated movies, with a special eye on Pixar. It is about a sausage in a supermarket. He goes on an epic journey to get back to his isle before the 4th of July, and reunite with his pack of sausage friends."

Seth Rogen and Evan Goldberg first made a name for themselves writing and producing 2007's Superbad. Their follow up was 2008's Pineapple Express. In 2013, they directed their first feature film This Is the End, and then returned in 2014 with the very controversial The Interview. Once you watch the first trailer for Sausage Party, you'll understand why this may be their most shocking and controversial movie yet! Warning: It is not for the faint hearted.
