Parts of it are so funny I was crying with laughter. You know the term "show stopper"? Have you ever actually seen a song stop a show? I have. In SOMETHING ROTTEN the audience response to two of the numbers is so prolonged and euphoric that it seemed like the actors wouldn't be able to continue.
The songs really, really sound like Mel Brooks wrote them for THE PRODUCERS with his orchestrator. Each a homage to brassy, old school, kick-your-heels-up Broadway show tunes.
Maybe the whole thing is so god damn funny and catchy because we have seen and heard it all before. It's highly accomplished Broadway comedy shtick with a Saturday Night Live twist keeping it fresh.
It has the same director as THE BOOK OF MORMON and if it comes to London it could be just as popular.
