While we don’t have 100% definite confirmation of this, fan site Batman-On-Film has apparently nabbed an early review of The Dark Knight following a Latin American screening of the film.
We’ll warn anyone looking to avoid spoilers that they should stay well clear, but it’s a very positive review of the movie, including a rave for Heath Ledger: “The guy delivered, got himself into the role and it's unrecognizable. There will be no other Joker after him." Yes, we’re as shocked as you to learn that the film will be good. Actually, that’s a big lie. We think it’s going to be amazing.
Those untroubled by learning a secret or two can proceed to the link.
