Warner Bros' underwater epicAquamanis a DCEU movie with a lot of goodwill behind it, partly becauseJason Momoais a sentient cloud of charisma, partly because trailers have teased a colorful feast for the eyes, but boiled down the film’s hype largely comes from the fact it’s being guided by directorJames Wan. The filmmaker has proven he can build an entire universe with theConjuringfilms while also displaying a knack for just blowing shit up withFurious 7, so this new behind-the-scenesAquamanvideo released today comes off as a mighty smart move from Warner Bros. If you want audiences to get excited for this massive comic book meal, show them how it got made.

“For me, the most important thing is the story I’m telling," Wan says in the video. “Whether it’s a scary set piece or a dramatic moment, it all comes down to the characters and if you care about them.”

The highlight is just how shockingly practical the costumes and sets look. There’s green-screen, definitely, but that’s actuallyNicole Kidmanlaid out on a rock. That’s Momoa chilling in a tank. That’s actuallyAmber Heardgetting blasted with tons of angry ocean wave effects.

“I fell in love with the project and fell in love with Mera,” Heard says. “She’s no damsel in distress. She’s a strong, badass, empowered superhero.”

And, if somehow none of that is interesting to you, know that the video is worth it for Wan’s delightful way of saying Aquaman as “Ackwaman” by itself.

Here’s the official synopsis forAquaman:

From Warner Bros. Pictures and director James Wan comes an action-packed adventure that spans the vast, visually breathtaking underwater world of the seven seas, “Aquaman,” starring Jason Momoa in the title role. The film reveals the origin story of half-human, half-Atlantean Arthur Curry and takes him on the journey of his lifetime—one that will not only force him to face who he really is, but to discover if he is worthy of who he was born to be…a king.
