Warner Bros. says its Jason Momoa-led, superhero picture "Aquaman" is now set for theatrical release on Dec. 21, 2018.
Deadline.com said the change came after James Cameron announced "Avatar 2" would not be ready on the desirable Dec. 21, 2018 date, as expected.
"Merry Christmas," director James Wan tweeted after the new Aquaman date was announced.
Momoa first played Aquaman in a cameo in 2016's "Batman v Superman: Dawn of Justice" and he will next be seen in the role in this fall's "Justice League."
The "Aquaman" standalone movie's ensemble will also include Amber Heard, Willem Dafoe and Patrick Wilson.
