From the studio that produces Robot Chicken, Hell & Back is an R rated stop motion animated film about two guys who have to save their buddy from hell, as boasts a ridiculous cast of Nick Swardson, T.J. Miller, Mila Kunis, Bob Odenkirk, Michael Pena, Rob Riggle, Danny McBride, Susan Sarandon, Brian Posehn, J.B. Smooth, Maria Bamford, Greg Proops, and Kumail Nanjiani. This has a lot of promise.
