The film is delayed due to the release of "Batman v Superman: Dawn of Justice". According to Jon Schnepp who directed the documentary of Tim Burton's cancelled movie "Superman Lives", Miller is expected to direct the sequel, reported Ace Showbiz.
"George Miller is doing Man of Steel 2. I don't feel weird about breaking it," Jon said in a recent podcast as quoted by Collider.
"Obviously Zack Snyder is doing Justice League one and two, James Wan is doing Aquaman. ... I think George Miller's a perfect choice to do Man of Steel 2. He's going to bring so much to it."
