I've seen this. It's very good. Stephen Chow isn't actually in it, he's just the writer/director/producer, but his trademark humor's still recognizable in the movie. The humor's a bit more overtly dark than some of his other work, like Shaolin Soccer and Kung Fu Hustle, but still quite funny.
Love me some Stephen Chow, can't wait.
