Without Superman the Movie there wouldn't have been Tim Burton's Batman Sam Raimi's Spider-Man Bryan singer's X-Men Christopher Nolan's Batman Patty Jenkin's Wonder Woman The MCU all of it wouldn't be possible without the Man of Steel if Snow White and the Seven Dwarfs is the Birth of a Nation of animated films(minus the racism)then Superman The Movie is the Birth of a Nation of Comic Book/Superhero films(again minus the racism)
Happy 40th Anniversary Superman the Movie!
