Director Zack Snyder announced the news on a live Q&A Wednesday, following a virtual screening of his Henry Cavill-led Superman film “Man of Steel.” The WarnerMedia streaming service, HBO Max, launches in just a week from today on May 27th.

THR is reporting that crucial decisions about the release are still up in the air. The ‘cut’ may be a 4 hour film or maybe even a six chapter mini-series. Now the Snyders (Zack and his wife/producing partner Deborah) duty is to bring in the actors for any dialogue touches, effect works, and even the score editing.

“It will be an entirely new thing, and, especially talking to those who have seen the released movie, a new experience apart from that movie,” Zack Snyder tells The Hollywood Reporter, noting that, to this day, he has not watched the version released in theaters.
“You probably saw one-fourth of what I did,” the director notes, basing his judgment on what has been shared with him of Whedon’s version.
Before Emmerich came calling, adds Snyder, “I always thought it was a thing that in 20 years, maybe somebody would do a documentary and I could lend them the footage, little snippets of a cut no one has ever seen.” 
But, adds Deborah Snyder, “With the new platform and streaming services, you can have something like this. You can’t release something like this theatrically, but you could with a streaming service. It’s an opportunity that wasn’t there two years ago, to be honest.”

Truly remarkable. I’m stunned. Congrats to all involved and especially to those persistent fans.
