Superman: Legacy is now in early development, and without any other DCU movies to distract for more than a year, fans are attempting to unearth every detail around the titular hero's iconic suit before the official reveal. This has garnered some pretty big bombshells as the ever-attentive James Gunn responds to as many queries and speculations as possible. So far, he has revealed much of the Superman: Legacy cast and the fact that Superman: Legacy will not be an origin story. Superman: Legacy is slated for release on July 11, 2025, when the DCU will commence in earnest.
