#3. The Dark Knight
Christopher Nolan didn’t set out to make sequels. After reenvisioning the Caped Crusader with 2005’s Batman Begins, though, Nolan couldn’t stop thinking about how his version of Batman would respond to the introduction of The Joker. The result was The Dark Knight, a hyper-real exploration of how chaos shakes up the mission of the righteous, complete with huge stars, incredible stunts, and an Oscar-winning performance by the late Heath Ledger.
One of The Joker’s creepiest tics in the film was his frequent lip-licking and cheek sucking. This wasn’t intentional but rather Heath Ledger’s genuine reaction to the uncomfortable prosthetics. But he was told to keep it for the character.
