Argo's Oscar-winning writer Chris Terrio has been hired to work on the Man of Steel sequel.
Warner Bros. have brought Terrio into the Batman-Superman fold to draft the script of Man of Steel 2 which will feature Argo director and star Ben Affleck in the role of Batman.
David Goyer has already written the film's screenplay but a source told The Hollywood Reporter that Terrio will get the script in shape before filming kicks off in early 2014.
Game of Thrones' Jason Momoa is reportedly in talks to star in the film and Gal Gadot has recently signed up to play Wonder Woman.
The currently untitled film is set for release in July 2015.
