Kiwi movie star Julian Dennison joked about doing 'meth' with Jimmy Kimmel as part of a hilarious interview that was broadcast as a gushing GQ profile on him was published.

The 15-year-old is currently doing media around the world to promote his new film Deadpool 2 and charming international audiences.

Dennison told Kimmel he'd been doing homework right before coming to the ABC studio, brushing up on his te reo Māori and math.

"Did you say 'meth'?" said Kimmel.

"Math - I do 'math' on the weekends," said Dennison

The pair joked about how the Hunt for the Wilderpeople star was too young to be allowed to watch Deadpool 2, and how he still shares a bedroom with his twin brother.

Kimmel also asked Dennison if his parents were happy about how much profanity is used in Deadpool 2.

"Yeah, they were fine with that - no they weren't," said Dennison.

"There was some stuff that got cut out of the film. There was one scene we were filming and Ryan whispered something in my ear and I was like, 'whoa, these virgin ears!'. It was pretty intense."

In the GQ feature, Dennison models for a photoshoot and chats at length about how he met Taika Waititi and what it's like living in Aotearoa.

He told the magazine he's not planning to move out of his home country any time soon.

"I love to chill with family, and I just love Christmas. It's during our summer. There's a camp called Brookfield Camp in Wainuiomata in Wellington, and we go there every Christmas," said Dennison.

"I've got 51 first cousins. Mum was from a family of 12. Nan - my grandmother - was from a family of 20. We have a lot of family and cousins, so it feels like a proper camp."

Deadpool 2 is currently in cinemas and made $1.787 million between last Thursday and Sunday in New Zealand, making it the country's biggest opening weekend ever for an R-rated film.
