Jason Momoa led a traditional Haka dance at the premiere of "Aquaman" in Los Angeles, after removing his jacket and necklace, and breaking a golden staff (Aquaman's weapon) in two.
A dozen relatives and friends joined Momoa on the blue carpet during the Marvel film's Hollywood premiere.
Haka is a type of ancient Māori war dance, according to NewZealand.com. The dance showcases foot-stomping, and rhythmic body slapping along with a loud chant.
Momoa drank Guinness after the traditional dance. He was joined by his wife and actress Lisa Bonet, their children and his mother at the premiere.
"Aquaman," the first full-length feature film centered around the character, will begin showing in U.S. theaters on Dec. 21.
The Aquaman character played by Momoa has appeared in previous films, "Batman v. Superman: Dawn of Justice" in 2016 and "Justice League" in 2017.
