Comic book movies used to be a niche before the 2000s, but they now lead the cinema industry, and audiences might not even know that the best comic book movies that aren't about superheroes are based on comic books. A billion-dollar-grossing sci-fi franchise, a deeply disturbing Korean thriller, and a Palme d'Or-winning LGBTQ+ drama are all adapted from comic books. While the Marvel Cinematic Universe, X-Men, and the DC Extended Universe reign supreme, a surprising number of other comic book movies that are unrelated to those universes have nothing to do with characters with superpowers.
