How is it even POSSIBLE!?!? The sequel to Batman Begins... the Dark Knight is celebrating it's 10th birthday today. That's crazy. Doesn't feel like it's been 10 years. It was July 18th, 2008 when it hit theaters everywhere. Some consider the Dark Knight one of best superhero movies ever made. Heath Ledger's portrayal of the Joker was literally the best part of this movie. With Dark Knight turning 10 today, that means it's been 10+ years since Heath Ledger has been gone too. Man, what a talent!
