A new Superman movie, Superman Legacy, is in the works from writer James Gunn. But its existence does not rule out the possibility of other Superman movies existing at the same time, including the rumored Superman film from author and journalist Ta-Nehisi Coates and producer JJ Abrams.
Gunn told io9 that his new Superman Legacy film is “totally unrelated” to other Superman projects, and the project from Coates and Abrams may live in the Elseworlds universe that exists outside of the official DC canon.
“Those two things are totally unrelated,” Gunn said. “That’s an exciting movie. I know that Chantal Nong, who is the executive on that project, is extremely excited about it. So if it comes in and it’s great, which I haven’t read the script, and if the timing is right, that could absolutely happen. That’s totally unrelated. It would be an Elseworlds tale like Joker.”
