“Nowhere does the [movie trailer] mention the fact that Sweeney Todd is a musical. In fact, it goes out of its way to conceal the fact that the movie is entirely sung, save for a few snippets of dialogue… Stung at paying to see a collection of tortuously constructed Stephen Sondheim tunes when they were expecting a gory Gothic thriller, a fair proportion of cinema audiences has been walking out of Sweeney Todd.”
