 A couple of other movies that were released on this day, highly regarded as the best Batman film. The Dark Knight was released on this day in 2008. You'll remember that one because that was the one that had Heath Ledger play the Joker. And it had one of my favorite quotes in all of Batman media, which is you either die a hero or you live long enough to see yourself become the villain. And that person that said it became a villain. Spoilers.
