A potential sequel to the DCU Superman movie and the DCU Supergirl film could pit the Kryptonians against a villain who still hasn't been in a movie.

According to Bloody-Disgusting, the late Return of the Living Dead actors James Karen and Don Calfa will appear in Linnea Quigley’s meta-sequel, Trash’s Revenge, “with the magic of CGI.” In response to a fan on Threads (via Screen Rant ), James Gunn confirmed he’s now “pre-writing” his next DCU project after Superman and Peacemaker season two.

Ultraman has been rumored to be the identity of the ambiguous, all-in-black villain seen multiple times across set images and trailers, but including this villain would be a mistake.
