Justice League: 10 Huge New Reveals About Zack Snyder's Reshoots 

Talking of The Joker, it turns out that his addition to the version of Justice League coming to HBO Max was one that was made since shooting finished the first time around. Unlike cast members Ben Affleck, Amber Heard, and Ray Fisher (who were no doubt always going to be needed for additional photography), there were no plans for Jared Leto to appear in Zack Snyder's original theatrical cut.

"No, he wasn’t," the filmmaker said when asked whether The Joker was going to be in his original theatrical cut. "There was a few things that I had thought about doing that I had thought about grabbing in post. There was a number of things I had drawn – a couple of them, I wasn’t able to do, but it’s fine. I’m completely satisfied."

"But this was one of the things that in the years since I’ve kind of boiled on and kind of said, like, this would be a cool thing to do. I’ll be honest, I never thought the opportunity would come, and thanks to the fans, of course, and this whole journey, it’s happened, which is insane."

This makes it clear that the Snyder Cut isn't just a finished version of the movie that the director made prior to Joss Whedon taking over; it's something completely new.
