CinemaCon attendees were treated to a new look at James Wan's Aquaman, with star Jason Momoa himself on deck to help introduce it. Wan and Momoa were joined by additional Aquaman cast members, including Patrick Wilson, Amber Heard and Yahya Abdul-Mateen II. The presentation was moderated by the voice of LEGO Batman, Will Arnett, who was told by Momoa that he's "the best f----n' Batman."

According to The Hollywood Reporterthe footage included Aquaman spouting signature one-liners, pulling a submarine from the ocean and "what appeared to be shark horses." The footage also showed off Atlantis and its landscape with a brief appearance from both Black Manta and Ocean Master.

Deadline also reports that the footage showed Atlanteans "riding sea horses" and "futuristic submarines." It seems as though Aquaman will challenge his brother Orm, aka Ocean Master, for the throne. The footage also found Mera asking Aquaman for help, in order to save "millions."

While the footage is the first extended look fans have seen of the upcoming film since last year's Comic-Con International, Wan made clear that what fans were seeing was just a first glimpse, not an official trailer, and that everything on-screen should be seen as a work in progress. "I didn't want to bring anything, but they made me," Wan said at the panel. In February, Wan stated that an Aquaman trailer was still a ways off.

Arriving in theaters on Dec. 21, Aquaman stars Jason Momoa, Amber Heard, Patrick Wilson, Yahya Abdul-Mateen II, Temeura Morrison, Dolph Lundgren, Ludi Lin, Michael Beach, Nicole Kidman and Willem Dafoe.
