Actress joins voice cast of the adult animation.

It has been announced that Susan Sarandon (‘Robot And Frank,’ ‘Jeff, Who Lives at Home’) has joined the ever increasing voice cast of the R-rated animated comedy ‘Hell & Back.’

The stop-motion feature revolves around two best friends (voiced by T.J. Miller and Nick Swardson) who must rescue their buddy when he’s accidentally dragged to hell. Sarandon will voice Barb the Angel.

Also lending their voices are Mila Kunis (‘Black Swan,’ ‘Family Guy’), Rob Riggle (’21 Jump Street’), Brian Posehn (‘Five Year Engagment’) and Kumail Najiani (‘Life as We Know It’), Danny McBride (’30 Minutes or Less’), Bob Odenkirk (‘Breaking Bad’), Kerri Kenney (‘Reno 911!’), Michael Peña (‘Gangster Squad’), and David Koechner (‘Anchorman’) among others.

Produced by ShadowMachine (‘Robot Chicken,’ ‘Moral Orel’), the film will be directed by Tom Gianas and Ross Shuman from a script by Hugh Sterbakov (‘Robot Chicken’).
