Deborah Snyder says Christopher Nolan supported her husband Zack in his quest to make the 'Snyder cut'

• Deborah Snyder said she and her husband are "good friends" with Nolan and his wife, producer Emma Thomas.
• "I think through this process it's been nice, because outside of Chris, Zack hadn't talked to a lot of people," Snyder said.

In the two years Zack Snyder stepped away from Hollywood to mourn the suicide death of his daughter Autumn, it has been Christopher Nolan who has been a close confidant to the "Justice League" director as he went forward with the "Snyder cut."

Snyder's wife and longtime producer partner, Deborah, revealed the close friendship to Insider, which goes back to when Nolan and his wife and longtime producing partner Emma Thomas enlisted the Snyders to take on the Superman movie "Man of Steel" back in 2013.

"They are very good friends of ours," Snyder said of the Nolans. "We have a lot of similarities: two husband and wife directing teams, they have a large family, we have a large family. I think our values are the same."

It was Nolan who was alongside Snyder when she watched the 2017 release of "Justice League" before it opened in theaters. After seeing it the two decided Zack should never see that version of the movie.

The theatrical release of "Justice League" was taken over by Joss Whedon after the Snyders left the project before filming wrapped following Autumn's death.

But when the #ReleaseTheSnyderCut efforts got to the point where WarnerMedia was willing to offer Zack the chance to make "Justice League" the way he wanted, Snyder said it was Nolan who was one of the people in their inner circle when Zack decided to finish what he started.

"I think for Zack he has a nice relationship with Chris," Snyder said. "A lot of times directors don't get to talk very often, so I think through this process it's been nice, because outside of Chris, Zack hadn't talked to a lot of people."

The four hour cut of "Zack Snyder's Justice League" will be released on HBO Max and in theaters internationally on March 18. It's extremely different than the version that was released in 2017, including a new beginning and ending to the movie. Despite all that, Snyder says only one new scene was filmed. The major lift was all the CGI. 2,656 new visual-effects shots have been put in the movie.

"It was an enormous undertaking," Snyder said. "Some of the effects we had to redo because it wasn't in our style. And Zack wanted to go back and put in some of the early character designs. We really put everything back in."
