Ngāti Haua descendant Julian Dennison makes a fiery debut in the upcoming Hollywood blockbuster, Deadpool 2.

The 15-year-old, who was born and raised in Naenae, Lower Hutt and has a major role alongside A-lister, Ryan Reynolds.

The young actor plays Russell Collins aka Firefist, an NZ orphan mutant with powers.

Dennison says Firefist's choreography was inspired by the haka.

“We looked at some haka and to bring the movements in that brought energy into it. I drew a lot of inspiration from haka.”

He said he even gave some te reo Māori language lessons to the Deadpool 2 cast.

“I taught them simple words like ‘kia ora’ and ‘mōrena’. They don’t know how to roll their tongue so some of the words sounded funny.”

Deadpool 2 comes out May 16.
