New scenes and story beats won't be the only things that differentiate Zack Snyder's Justice League from the 2017 theatrical cut.
Speaking on a panel at this past weekend's Justice Con, Snyder said the entire film will stream in its original IMAX aspect ratio. "My intent was to have the movie, the entire film, play in a gigantic 143 aspect ratio on a giant IMAX screen," he said. "Superheroes tend to be, as figures, less horizontal. Maybe Superman when he's flying. But when he is standing, he's more of a vertical. Everything is composed and shot that way, and a lot of the restoration is trying to put that back."
Snyder said that film was originally shot in the 1.43:1 aspect ratio, but the film had to be cut to fit most theater screens, which are not as tall as IMAX. He pointed to the clip he shared in June, where Wonder Woman learns about Darkseid, as the first example of what the film will look like on HBO Max. (His comments start around 15:30 in the video below.)
Snyder will debut the first trailer for his cut during DC FanDome on August 22. He also plans on revealing the movie's real title at the event and will announce whether the project is going to be a TV miniseries or a full-length feature.
The announcement of the Snyder Cut ended the two-and-a-half-year movement that pushed for its release. It began when the film first premiered in theaters following reports that Snyder's version of the movie had been heavily altered by Warner Bros. and new director Joss Whedon after Snyder had to step down due to a family tragedy. Many blame those two parties for the film's subpar critical reception and argue that Snyder's product is far superior and fits more coherently with his previous two films in the DCEU canon: Man of Steel and Batman v Superman: Dawn of Justice.
Justice League 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, Ciarán Hinds as Steppenwolf, Jesse Eisenberg as Lex Luthor and J.K. Simmons as Commissioner Gordon. Zack Snyder's Justice League will premiere exclusively on HBO Max in early to mid-2021.
