During Justice League's Atlantis scene, Mera constructed an air bubble so that she could talk with Aquaman, which made some fans worried that dialogue in James Wan's upcoming Aquaman film would occur similarly, but the director has now said that conversations won't take place that way.
"Fret not, no 'air bubbles for dialogue' in my underwater world," Wan wrote on Twitter. He did not explain how Aquaman will otherwise handle its underwater dialogue scenes.

Although Amber Heard makes her big-screen debut as Mera in Justice League, a number of scenes featuring Aquaman and Atlantis were left on the cutting room floor, likely a result of the film's studio-mandated 2-hour runtime. Willem Dafoe, who was set to make his debut as Vulko in Justice League, was also cut from the movie.
Aquaman will mark the character’s first solo outing on the big screen and has been described as "Star Wars underwater," with Wan promising that fans can expect a "swashbuckling action-adventure, sort of high seas adventure story."
Arriving Dec. 21, 2018, Aquaman stars Jason Momoa as Aquaman/Arthur Curry, Willem Dafoe as Nuidis Vulko, Amber Heard as Mera, Patrick Wilson as Ocean Master, Yahya Abdul-Mateen II as Black Manta, Temuera Morrison as Thomas Curry, Dolph Lundgren as Nereus, Nicole Kidman as Atlanna, Ludi Lin as Murk, and Michael Beach as Jesse Kane.
