Production got under way on the highly-anticipated Justice League last month in the U.K., with Zack Snyder at the helm, but we have yet to get any story details or an official cast list from Warner Bros. as of yet. We haven't heard anything about the production thus far, aside from the movie adding J.K. Simmons as Commissioner Gordon and Willem Dafoe in a mystery role, and bringing back Jeremy Irons as Alfred from Batman v Superman: Dawn of Justice, along with the previously-confirmed Justice League members. While we wait for more details, Jason Momoa has given us another glimpse at his Aquaman look in a new photo.

The actor took to his Instagram page earlier today to share a new photo, presumably from the Justice League Part 1 set, where he's seen sporting his elaborate Aquaman tattoos and full beard. The actor is seen holding up a sign to support a movement called Rezpect Our Water, which is trying to stop an oil pipeline from crossing the Missouri River near the Standing Rock Sioux Tribe Reservation in Fort Yates, North Dakota. Here's what the actor had to say about supporting this cause.

Justice League Part 1 is shooting at Leavesden studios in southeast England, and will utilize on-location shoots in London and Iceland. It was originally rumored that Justice League Part 1 and Justice League Part 2 will be shot at the same time, but that report was recently debunked. Warner Bros. has slated Justice League Part 1 for release on November 17, 2017, with Justice League Part 2 arriving in theaters on June 14, 2019. It isn't known when shooting will commence on Justice League Part 2, but we'll keep you posted with more details as soon as we have them.

Last month, Jason Momoa shared a brief video from one of his Justice League workouts, but that's about the closest thing we've seen to any sort of footage thus far. Hopefully we'll get our first look at the entire Justice League together, including Batman (Ben Affleck), Superman (Henry Cavill), Wonder Woman (Gal Gadot), The Flash (Ezra Miller) Cyborg (Ray Fisher) and Aquaman. Until then, take a look at Jason Momoa's Aquaman photo from the Justice League set.
