There's a new movie on hell coming out this Fall...
It's a documentary and includes such people as: Brian McLaren, Bob Larson, Justin Taylor, Kevin DeYoung, Mark Driscoll, Greg Boyd, Peter Kreeft, and Frank Schaeffer. It also includes someone called "Oderus Urungus" who is billed as a vocalist from "Gwar"--he looks as weird as his name (he's the "guy" on the right; guy on the left is Dee Synder).
You can check out trailer for the movie and comments from director on the official website: Hellboundthemovie.
