James Gunn has addressed the rumours surrounding the sequel to Superman (2025), Man of Tomorrow. This comes after Gunn posted a photo of the sequel's script which had a cross section anatomical image on the cover.

Speaking to Entertainment Weekly, Gunn said, "Listen, of course I wasn't unaware that when I posted the cover of the script that there was going to be discussion around that particular topic. But I think we'll hold off from what exactly is happening."
