Aquaman made waves at the CinemaCon when director James Wan surprised the crowd with the first ever footage of the standalone DC film.

The director, who attended CinemaCon in Las Vegas alongside cast members Jason Momoa and Amber Heard, had a little something for the DC fans present on Tuesday, April 24.

The First Peek At 'Aquaman'

Wan, who helmed horror flicks Saw, The Conjuring series, and Insidious, told the crowd that he didn't actually want to let audiences see what he has in store for them yet.

"I didn't want to bring anything, but they made me," Wan quips before starting the video on the screen.

According to The Wrap, the new footage of Aquaman shows Momoa's Aquaman — a.k.a. Arthur Curry — returning to the underwater kingdom Atlantis to go up against his brother Wilson's Ocean Master for the throne. Heard's character Lady Mera pleads with the hero to help defend Atlantis, but he's uncertain if he's the man for the job.

"I'm a blunt instrument, and I'm pretty bloody good at it," Aquaman tells Mera in the teaser.

The teaser also included clips of the stunning Atlantis seascape, warriors riding sharks like horses, and Abdul-Mateen's Black Manta looking just like he does in the comic books, according to ComicBook.com's Brandon Davis.

While the film is still very much a work in progress, a report in Variety reveals that Wan told the crowd at CinemaCon that he hopes they would be able to "catch a glimpse of something that may represent the fun film I'm going for."

Fans have been clamoring for a glimpse of the upcoming Aquaman movie for a while now with the uproar over it getting so loud that Wan even addressed it on Twitter.

"It's not because of anyone or any nefarious reason holding it back — IT'S ME," he says in a three-part tweet last March. "I am simply not ready yet to share. This movie is filled to the gills with VFX, and the process is as slow and laborious as a sea-slug! Yes, even shots for the trailers take forever to do, and I refuse to put out anything that might be construed as subpar."

Aquaman is slated to hit theaters on Dec. 21.

Across The DC Extended Universe

The DC team at CinemaCon also dropped a couple of details on the other films slated as part of the extended universe, according to a report from Deadline.

Some of the tidbits scoped out from CinemaCon include director Patty Jenkins confirming Wonder Woman 2 will be set during the '80s.

Shazam! director David Sandberg also had his share of the spotlight with a few clips of the film starring Zachary Levi shown during the panel.
