Stephen McFeely and Christopher Markus, writers of Avengers: Endgame were asked at San Diego Comic-con if which DC superhero they'd like to make and they suprisingly answered Superman.
"I mean, I think Captain America shows there are certainly ways to do a really good Superman movie in this day," McFeely added. "You don't have to dirty him up, you don't have to get rid of his earnestness. I'm a big — the Christopher Reeve Superman is one of my favorite movies. So that's one we certainly borrow from all the time."
David S. Goyer and Zach Snyder took a diffrent approach on Man of Steel, which they tried to modernize the character by forcing him to make difficult decisions like killing General Zod in the battle of Metropolis. Whereas McFeely and Markus took a different approach for Steve Rogers in all Captain America movies, Avengers: Infinity War and Avengers: Endgame. They embraced all the dull qualities of Roger that makes him a strong character.
Markus and McFeely are already done with their projects to Marvel and they have no other future projects with them, but that they're open to return under the right circumstances.
Markus said in an interview: "We don't know yet, but we certainly have no desire never to return," "We're not on anything at the moment, and we're going to do a few things for the studio that we founded with the Russo's. But you know, this has been an amazing experience, and we'd be fools to say that."
Theres still no news for Superman on big screen but fans are hoping for him to return.
