Momoa's son and daughter, Nakoa-Wolf and Lola, got in on the action, too.
It was a red carpet unlike any other as Jason Momoa and cast members from the movie "Aquaman" performed a haka chant at the movie's Los Angeles premiere Thursday night.
The haka is a traditional dance that comes from the Maori culture of Polynesia and New Zealand.
The New Zealand All Blacks rugby team perform it ahead of matches in an effort to intimidate opponents.
Momoa took to the red carpet Thursday night with a gold trident, Aquaman’s signature weapon, and began the chant by taking off his jacket.
Soon after, other actors from the film joined in, some by stripping off their shirts, others by rolling up their sleeves to perform the ceremonial chant.
The particular haka Momoa performed with his castmates is called Ka Mate. The 39-year-old, who is of native Hawaiian descent, told "Entertainment Tonight" the Ka Mate was a way of honoring his heritage and the water.
Among those joining Momoa were New Zealand actor Temuera Morrison, who plays Aquaman's father in the film.
Momoa's son and daughter, Nakoa-Wolf and Lola, got in on the action, too.
"Aquaman" hits theaters Friday, Dec. 21. It also stars Nicole Kidman, Willem Dafoe, Amber Heard, and Dolph Lundgren.
