Just saw the clip they played at ComicCon 2006, including Jack Black confirming the November 17th release date and Meat Loaf singing (briefly) while scolding a young Jack Black

Looks great!

He's probably just in this cameo, as
Rolling Stone says that Black leaves his home and his uptight Christian father behind at the start of the film.
