Warner Bros has begun negotiations with the Dark Knight Rises director to have complete control of the DC cinematic universe, according to Latino Review, who are known for their Marvel movie scoops.
The supposed deal, if concluded, would mean that Nolan would oversee every upcoming DC superhero project.
Nolan would allegedly produce the Justice League movie with Man of Steel's Zack Snyder, who may direct the film.
His arrival would also reportedly allow Warner Bros to secure Christian Bale to return as Batman for a fourth time, alongside Henry Cavill's Superman.
Nolan previously said that The Dark Knight Rises would mark the end of his Batman story.
Last month, it was alleged that Warner Bros demanded a page-one rewrite of Justice League by Gangster Squad writer Will Beall.
A Batman movie reboot is also said to be in the works, and is rumoured for a 2017 release.
