The Flash costume in Batman v Superman revealed? First trailer update for The Justice League

While fans look forward to the release of Batman v Superman: Dawn of Justice in March, director Zack Snyder, Warner Bros and team have kicked off production for The Justice League film in the UK.

Justice League - Part 1 will begin filming on 11 April, a little over two weeks after the release of Batman v Superman: Dawn of Justice, Snyder told Entertainment Weekly. "The idea that we could begin to boot up a Justice League concept was a cool thing," said the director, who is also the main architect of the DC Cinematic Universe at Warners.

"It was a little bit of an 'about time' moment, and I don't blame [the studio] for feeling that way, because it's a long time coming," he said. "But I do feel like it's a little bit of a creative hurdle. It seems like an easy thing to do at first glance, the idea that, 'Oh, we just get the rest of the superheroes in there.' But you have to [establish] a world where they can exist."

Justice League will be shot at the Warner Bros Leavesden studios in southeast England, as well as in various locations around London and in Iceland. Snyder is currently in the UK prepping for the start. He recently tweeted an image with Aquaman star Jason Momoa — don't miss The Flash costume in the background.

The Flash will be played by Ezra Miller. He is rumoured to be showing up as a cameo in Batman v Superman but will appear in Justice League ahead of his own standalone film in 2018.

Meanwhile, with filming set to begin in April, it's safe to assume that the makers may showcase a first teaser trailer of The Justice League at the 2016 Comic-Con in July.
