Anything Goes : Name That Film... by Nick Belial

Ok, so here's a little trivia question for the group: This 1990's film, _____________________________________ had a cast member who later went on to play a prominent roll as a vampire in a well known film franchise. In another of his films, he plays the part of an aging singer-- looking for a comeback. That movie, by the way, seems to get a lot of play each year around the holidays. And oddly enough, this same actor also plays a washed-up rocker whose band is having a reunion tour-- and hoping for a comeback-- and that's the movie that you're trying to name here. One last clue... There's another actor in this unnamed film, who also has an integral role in several of the Harry Potter films. Name the film: _____________________________________
