Trailer for True Grit

I'm very much looking forward to seeing the Coen brothers' rendering of True Grit, Charles Portis's hilarious, violent and touching Western novel. (For some reason I'm thinking it as a film version of the book, not just a new version of the John Wayne film.) But this trailer seems a bit too serious to me - Portis's novel is much funnier than what we see here. Maybe it's the music.

Or then it's just the trailer.
