An alternate trailer for Batman: The Dark Knight has appeared online. With Iron Man released and The Incredible Hulk out now, Batman is the next big blockbuster on the way.

The alternate trailer has mostly footage we've seen before but all assembled together. It definitely looks like the most complete trailer we've seen.

Batman: The Dark Knight is released in July. You can see the alternate trailer below, Batman, Joker and Harvey Dent are all in there. It comes from Comcast On Demand through Coming Soon. Man this looks good, I can't wait to see Heath Ledger's Joker.
