The cast of Aquaman, led by Jason Momoa, performed the haka at the movie's premiere in Hollywood.
Momoa performed the traditional Maori dance midway through the film's premiere on Wednesday.
His kids, as well as co-star Temuera Morrison, who plays Aquaman's father, all joined in on the action.
Momoa got so into it, he smashed his trident in half.
"It's an offering and a beautiful moment," he told E!
"It just happened. They (my kids) were like 'can we do it?' and I was like 'yeah'."
