They're not on film, but check out Book of Mormon and Avenue Q. They're both hilarious.
Those are awesome. I laughed so much at
Book of Mormon that it actually just hurt to laugh by the end.
I haven't seen the movie
Rock of Ages yet, but from what I've seen/heard so far, it sounds like they really screwed up all of the things that made the stage version so much fun.
And keep in mind...I didn't even want to see
Rock of Ages on Broadway. I saw a matinee in the cheap seats with a friend, and we wound up loving it so much that we're nearly went back for the evening show to see it again.
What made the stage version of
Rock of Ages work was that the music was the star. I grew up in the 80s, so that was my music. If it was sung badly, I wouldn't have enjoyed it. But the cast was so incredibly talented, and they just rocked the hell out of those songs. I can listen to the cast recording and enjoy it almost as much as the originals.
Just going by the movie soundtrack, half the cast sounds like they're going for a
Glee audition.
And the story is paper-thin. But again, what made the stage version work is that the show knew how stupid it was, and the narration (which I hear is gone in the movie) kept pointing that out to the audience. At point one character tries to cheer up the other by pointing out how he wanted to be a serious actor "and now I'm stuck in a show with boob jokes and Whitesnake songs!"
Also, the ending (from what I've read about the movie) in the show was much funnier. It's completely different in the movie.
I wasn't sure how it would translate to a film, since the success of the show hinges on hearing that music live and the way they play with the audience, but it sounds like it should have been much, much better.
