Evil witch pursues eternal youth of a fallen star in 'Stardust'

If De Niro's drag routine makes as much sense in Stardust as a kazoo solo inserted into a Mozart string quartet, it makes movie-trivia sense if you think of it as a response to Johnny Depp's fey Pirates of the Caribbean character, Jack Sparrow. In that case, this joke about a joke is either a piece of inspired madcap fun or an excruciating embarrassment.
