The thing to remember about Superman: The Movie is that nobody had ever made a live-action feature-length superhero movie before, so they didn’t have any preconceived ideas of what a superhero movie was supposed to be like. It could go in almost any direction: science-fiction, fantasy, drama, fairy tale, action-adventure. Should it be aimed at kids, or adults? How scary should it be?
The movie that they ended up putting together is famous for changing tones throughout the prologue: the glitter opera of Krypton segueing into Norman Rockwell in Smallville. The teen football scene could fit into a contemporary live-action Disney film with no questions asked; one of these days, I’m going to get around to writing that Superman/Escape to Witch Mountain comparison that American film criticism has been waiting for all these years.
But the most important tone shift happens right here, in our first visit to the Daily Planet. This is when the story really begins, and we find out what a Superman movie sounds like. The answer, thank goodness, is screwball comedy.
