There are many reasons we watch superhero movies, but the new 'Superman' reminds us why we fell in love with superheroes in the first place.

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.

As 'Superman' continues to dominate the domestic box office after two weeks, James Gunn is commenting on the movie's international performance.
