An A-lister makes an appearance in the new "Superman" movie, in reference to the hero's origin story.

DC Studios’ new Superman movie feels like a wild comic book that’s been brought to life. For years, Warner Bros. Discovery has been playing a desperate game of catchup in hopes of recreating the success that Marvel achieved with its live action comics adaptations.

This means that future DCU movies and series don’t need to only move the story forward. They can also take things back in time. A period story about a metahuman from 100, 200, or 300 years ago is perfectly acceptable. This opens up possibilities for different sorts of stories in a way that the MCU has largely had to rely on the multiverse to tell.
