Justice League was a movie that already had a lot of moving parts before director Zack Snyder and producer Deborah Snyder had to walk away because of a terrible tragedy. Producer Charles Roven spoke to NewsDay

"I heard about it fairly soon after the event," Charles Roven, a producer of DC's films going back to "Batman Begins" (2005), says gingerly. "It was absolutely devastating emotionally. And in true Zack and Debbie style," he says, referring to fellow producer Deborah Snyder, Zack's wife and Autumn's stepmother, "they took the time to grieve and then went back to stay the course." When they no longer could, "Everybody completely understood." With Whedon — who wrote and directed Marvel's two Avengers movies before decamping to DC to develop a Batgirl film — already working on "Justice League," he was, says Roven, "the natural individual to go to, to see if he were willing to step in and finish the movie."

Roven went on to talk about seeing where Snyder and Whedon cross when it comes to the movie.

"I really don't know how to break down the scenes that [Joss] wrote with Zack versus the scenes that he wrote later," Roven says. "If you take 'Man of Steel,' 'Batman v Superman' and 'Justice League' as a trilogy — they were all directed by Zack, with the third one having some influence by Joss — I would say this is the lightest of the three. That doesn't mean it's a comedy!"

A comedy is the last thing we thought Justice League would be. Fingers crossed though.

Summary: Fueled by his restored faith in humanity and inspired by Superman's selfless act, Bruce Wayne enlists the help of his newfound ally, Diana Prince, to face an even greater enemy.

Justice League, directed by Zack Snyder, stars Ben Affleck, Gal Gadot, Jason Momoa, Ezra Miller, Ray Fisher, and Henry Cavill. It will be released on November 17th.
