Man from U.N.C.L.E. star Armie Hammer once had a brush with the Dark Knight. The star was cast as Batman in George Miller's doomed Justice League: Mortal project, which featured the team's classic lineup of characters. Speaking to ScreenRant, Hammer discussed his time with Justice League: Mortal and revealed that he even got to try on the Batsuit -- which looked more like an exoskeleton than the traditional cowl.

“Oh yeah, for sure. I put on the whole suit. Weta made our suit. It was all functioning. It had like carbon fiber, and it had like pistons and gears that would function. It was amazing! It was like a exoskeleton suit,” he shared.

Justice League: Mortal entered production a decade ago in 2007. In addition to Hammer, the film was set to star Megan Gale as Wonder Woman, Common as Green Lantern and Adam Brody as the Flash but ultimately fell through due to poor planning. However, in Miller's own words, the movie simply wasn't meant to be.

“Justice League was the main one,” Miller, who went on to direct Mad Max: Fury Road, explained in an interview last year. “That was, oh, seven years ago, I think. And there was a really great script. And Warners said, ‘Let’s do it. Let’s do a Justice League.’ I really was attracted to it. But there was a writers strike looming. We had to cast it very quickly, which we did with Warner’s casting people. And we cast it really quickly and we mounted it very quickly. And it depended on a start date and it depended on some basic rebate legislation that had just got through a new Australian government. But it was just too big a decision for them to make in the time. And that fell through and the whole film fell through. We almost got there. And it wasn’t to be. But that happens a lot, where films line up and the stars look like they’re aligning and they didn’t.”

Fortunately for DC fans, the Justice League will finally hit the big screen this summer -- even though Miller won't be behind the camera. Arriving November 17, Justice League stars Ben Affleck as Batman, Henry Cavill as Superman, Amy Adams as Lois Lane, Gal Gadot as Wonder Woman, Jason Momoa as Aquaman, Ezra Miller as The Flash, Ray Fisher as Cyborg, Willem Dafoe as Vulko, Jesse Eisenberg as Lex Luthor, Jeremy Irons as Alfred Pennyworth, Diane Lane as Martha Kent, Connie Nielsen as Queen Hippolyta and J. K. Simmons as Commissioner Gordon.
