The Hollywood Reporter reported that Autumn was 20 when she died by suicide in March, and that Snyder never intended to make the news public.
However, when he decided it was time to step away from work, "I knew there would be narratives created on the internet... [but] I'm past caring about that kind of thing now."
“The demands of this job are pretty intense. It is all-consuming," he told the publication. "I’ve decided to take a step back from the movie to be with my family, be with my kids, who really need me. They are all having a hard time. I’m having a hard time.”
A rep for Warner Brothers, the distributor of the film, confirmed the report to ABC News.
"He’s handing the baton to Joss, but the course has really been set by Zack," Emmerich said. "I still believe that despite this tragedy, we’ll still end up with a great movie.”
Snyder, who has seven other children, agreed, but said that right now he can't think about the film.
“I want the movie to be amazing and I’m a fan, but that all pales pretty quickly in comparison," he said. “I know the fans are going to be worried about the movie, but there are seven other kids that need me. In the end, it’s just a movie. It’s a great movie. But it’s just a movie."
A rep for Snyder had no comment.
