Just saw a super slick reel of Aquaman concepts. It included people riding sharks underwater described as a dogfight. Wan has a great vision

Aquaman concept art footage looks epic. Sci-Fi underwater with a LOTR vibe to its design too. Lots of creatures. Manta helmet looks accurate

Notably, Jason Momoa -- who plays the titular King of Atlantis -- also revealed that he's headed to Australia to begin filming. The movie doesn't come out until winter 2018, so there's still plenty of time for Momoa to shoot this solo "Aquaman" film. Aquaman will also play a prominent role in "Justice League," which just dropped its first trailer and releases this November.

Momoa wasn't the only member of the Justice League present at CinemaCon. Zack Snyder, who directed "Batman v Superman: Dawn of Justice" and heralded in the DC Extended Universe, snapped a photo of Ben Affleck (Batman), Ezra Miller (Flash), Ray Fisher (Cyborg) and Henry Cavill (Superman) and shared it on Twitter as well.

Screen Actors Guild Award nominee Jason Momoa will play Aquaman.
