Director Joss Whedon will oversee the remainder of Snyder's duties on the Warner Bros. film, which is currently in post-production.
While the main filming on "Justice League" has wrapped, Whedon will help with reshoots, editing and other post-production work for the film to meet its current Nov. 17 release date.
Warner Bros. didn't immediately respond to a request for comment. Neither did representatives for Snyder and Whedon.
Whedon has also been slated to direct the upcoming "Batgirl" film, so this could be a good fit for the director to get in the DC Comics mindset after being involved with Marvel's "Avengers" so for long.
