"I'm incredibly grateful for your enthusiasm and kind words over the past few days," Gunn wrote in an Instagram Threads post following the film's successful opening weekend

Director Richard Donner’s Superman: The Movie, which premiered in 1978, is a classic piece of cinema that continues to shape the superhero genre today. Most recently, it led the way for writer-director James Gunn to release Superman, a more modern imagining of the Man of Steel’s adventures, with David Corenswet portraying the titular hero.

Now that Superman is finally back in theaters, it’s time to revisit his old adventures.
