Justice League Snyder Cut trailer At DC FanDome in August last year, we got the first teaser trailer for Zack Snyder's Justice League, where the director also revealed that it would be four hours long. Due to music copyright issues, it had to be pulled down later. Hence in November, it was reuploaded with proper clearances alongside a black-and-white version of that same teaser trailer — save for a few different shots. And then in mid-February, we got the official trailer that came with a bunch of new footage, including from the October 2020 limited reshoots Snyder undertook. HBO Max surprised us with a final trailer in the week of release, that gave us a better look at the villains, Steppenwolf and Darkseid, and their plans.
