Mila Kunis has joined the cast of Shadowmachine’s R-rated stop-motion horror-comedy Hell & Back. The 28-year-old stunner will voice the character of Deema, a rogue demon who is also part human.

Directed by Tom Gianas, Hell & Back tells the story of two friends who embark on a journey to hell to save a buddy. Costars include Nick Swardson (“Reno 911”), TJ Miller (How to Train Your Dragon), Rob Riggle (The Lorax), Brian Posehn (Surf’s Up) and Kumail Najiani (“Franklin & Bash”).

Kunis, whose voice work can be heard on the long-running Fox series “Family Guy” and on episodes of Adult Swim’s “Robot Chicken,” will next be seen in Seth MacFarlane’s insanely hilarious comedy Ted and in Sam Raimi’s Oz, the Great and Powerful.
