The Joker is arguably one of the most famous villains of all time. Seriously, he’s one of the only villains to successfully cross over into multiple mediums. He’s been legendary across live-action TV, animated TV, live-action films, animated films, and even video games. Pretty impressive for a comic book character. He’s been played by legendary performers, including Cesar Romero, Jack Nicholson, Mark Hamill, and Heath Ledger (and yes, I’m leaving a certain someone off the list of “legendary” performers).
