EXCLUSIVE: Nick Swardson and TJ Miller have been cast in ShadowMachine’s R-rated stop-motion animated Hell & Back, a comedy about two best friends who must rescue their pal when he is accidentally dragged to hell.

Miller, a fellow stand-up, recently landed a lead in Fox’s comedy pilot Little Brother. He is repped by WME and 3 Arts.
