The production of the Justice League movie has been fascinating to follow, thanks in large part to its behind the scenes shake-ups. In the wake of the news that Joss Whedon took over the film from Zack Snyder in the later days of shooting, fans have been curious exactly how much of the movie should be credited to Whedon. After all, he changed enough of the movie to earn himself a writing credit. So how much of the movie did he direct?

According to producer Charles Roven (as reported by ABC), Whedon didn't really direct that much of what we will see on the screen.  "That imprint that Joss had, some aspect of it is going to come out in the direction, but the actors are already pretty much down the road on their arcs," Roven said. "Let's just say 80, 85 percent of the movie is what was originally shot. There's only so much you can do with other 15, 20 percent of the movie."

Roven specifically credited the tone and feel of the movie to Snyder, who spent years setting the movie up. It seems that Whedon took his cues from Snyder, and not the other way around. "The goal is to make sure when you're watching the movie, it all feels cohesive,"Roven said, and the cast agreed.

"Zack from the time that I first met with him said, 'Look, Batman makes the DC world dark. The DC world has to be created as something dark,'" Ezra Miller, who plays the Flash, added. He went on to say that the movie is true to "Zack's vision" and that what is on the screen was "the intention from the beginning."

Justice League hits theaters on Nov. 17 and stars Ben Affleck as Batman, Gal Gadot as Wonder Woman, Henry Cavill as Superman, Amy Adams as Lois Lane, Jason Momoa as Aquaman, Ezra Miller as The Flash, Ray Fisher as Cyborg, Jeremy Irons as Alfred Pennyworth, Diane Lane as Martha Kent, Willem Dafoe as Nuidis Vulko, Ciarán Hinds as Steppenwolf, Jesse Eisenberg as Lex Luthor and J.K. Simmons as Commissioner Gordon.
