Thanks to a 2024 retcon, 1989s Batman now includes the cinematic debut of a classic DC villain. 1989s Batman was a game-changing success for not only Batman’s live-action movie landscape, but also the superhero genre and the way big-budget blockbusters are marketed. The film made Batman DC Comics and Warner Bross most marketable superhero property and directly (or indirectly) led to a slew of beloved superhero properties, from various sequels and reboots to the DC Animated Universe itself.
