A friend of mine asked me about a movie he saw when he was 8. The ending was something along the lines of some teenagers going through hell, rescuing a girl, and leaving and coming back to the world from a coffin at a funeral.

Any takers? I have a couple of other movies I've been wondering myself about, but that'll be a question for another time.

Sounds like Highway to Hell (1992) (http://www.imdb.com/title/tt0104418/)
