Earlier today,Justice LeagueandJustice League Part 2directorZack Snydershot down rumors that Warner Bros. may delay the two-part movie, confirming that production is scheduled to begin April 11 at Leavesden Studios in the U.K. For those who want even more proof, the director took to hisTwitterpage earlier today, sharing a new photo withJustice LeagueandAquamanstarJason Momoaat Leavesden. The most intriguing part of the photo is in the background, which offers an early look at the fullAquamancostume, along withThe Flashsuit and what could be the costumes for Mera and Nightwing. There is also a painting of Mera propped-up on the floor.

We’ve known ever since Warner Bros. announced their fullDC Comicsslate in 2014 thatEzra Milleris playingThe Flash, but we still haven’t seen our first look at the official costume yet. We did get to seeconcept artfeaturing the costume last month, but it remains to be seen when we’ll get our first look atEzra Millerin costume. As forAquaman,Zack Snydergave us our first official look atJason Momoalast February, but we still have yet to see his full costume, until now.

We reported last month thatAmber Heardis in talks to play Mera in both Justice League Part 1 andAquaman, but it isn’t known if she has officially signed on. Just below The Flash costume in the background, there is a portrait of what appears to be concept art of Mera, but we don’t know for sure. The character is described as the “Khaleesi of the sea,” borrowing a term from HBO’sGame of Thrones, whichJason Momoaused to star on. As for Nightwing, this character hasn’t been confirmed for any of the DC movies, and we don’t know for sure if that’s his costume either.

All of theJustice Leaguecharacters are said to be introduced at the end ofBatman v Superman: Dawn of Justice, withAquaman, The Flash andCyborg(Ray Fisher) uniting with Batman (Ben Affleck) Superman (Henry Cavill) and Wonder Woman (Gal Gadot). The studio still hasn’t cast anyone forGreen Lantern Corps.yet, but that movie is expected to feature a number of different Green Lantern’s, including Hal Jordan and John Stewart.

Justice League Part 1will also be shot on location in London and Iceland, but sadly no plot details have surfaced quite yet. Of course, next month’sBatman v Superman: Dawn of Justicewill set the table for this two-part adventure, and it’s surely no coincidence that filming will begin afterBatman v Superman: Dawn of Justicehits theaters on March 25. While we wait for more onBatman v Superman: Dawn of JusticeandJustice League Part 1, take a look at this intriguingJustice League Part 1photo below.
