Justice League will begin filming on April 11, 2016 and Zack Snyder recently tweeted this photo of himself and Jason Momoa (Aquaman) from Warner Bros. studios in Leavesden, England where the movie is currently under pre-production.
In the background we get a glimpse of The Flash costume which will be worn by Ezra Miller. We also see the Aquaman costume which has been revealed in the past, along with a set of black body armor which is likely a costume for Aquaman villain Black Manta or a base for a Green Lantern costume. Also seen is a mannequin with a scarf around its mouth. Right below the Flash costume is a concept art painting of Mera, who will be the wife of Aquaman.
On the extreme right side of the photo below we have a sliver outfit with large shoulder pad.
When I originally saw Zack Snyder tweet this photo, my initial thoughts were how exhausted he looked. He has lost quite an amount of body weight and is obviously under ton of pressure. I have qualms about Man of Steel, though there are some aspects of the movie I enjoyed there are also certain things about the character I wished were done differently. I am still very hopeful about Batman v Superman and I have no doubt Ben Affleck will do justice to the character of Batman, but also counting on Superman to be a worthy opponent who will have a better comeback in this movie. Snyder is passionate about these characters and the franchise as a whole is riding on him. I am rooting for Snyder to succeed like I always have.
