Brad Pitt looked unrecognisable on the set of his new film in New Zealand on Sunday.

The Hollywood star, 61, sported a beard and green beanie as he filmed scenes for his upcoming movie Heart of the Beast in Kinloch.

The actor wore cargo pants and a camouflage-print top as he stood near a fire pit and bright yellow tent.

He was also seen kayaking across the lake in a green canoe before filming scenes at the campsite.

At one point, Pitt was seen chatting to the film and camera crew before getting back into character.

The actor quietly slipped into New Zealand last month to film his latest blockbuster.

He was spotted at Auckland airport ahead of his work on the action film.

The story centres on a former US Navy SEAL who becomes stranded in the rugged North American wilderness with his retired ‘combat dog’.

Locations on NZ’s south island, including Queenstown, will be used to ‘stand-in’ for Alaska, where the story is set.

According to Stuff, Pitt will remain in Auckland to attend to pre-production meetings before filming, which will begin next month.

The world-famous tourist destination of Milford Sound (Piopiotahi), a fjord known for its stunning scenery and beautiful mountain peaks, will also feature as a location.

The new film will see Pitt once again working with filmmaker David Ayer who directed the legendary heartthrob in the 2014 World War II action film, Tank.

Pitt’s successful production company Plan B are producing the film for Paramount Pictures.

The Otago Daily Times reported that the movie is expected to be filmed over seven weeks.

It comes as Pitt’s new blockbuster F1 will be heading into cinemas Down Under in June.

Set in the high-stakes world of Formula 1 motor racing, Pitt plays a champion driver who comes out of retirement to challenge a young up-and-comer.

Directed by Top Gun: Maverick filmmaker Joseph Kosinski, F1 co-stars Oscar-winner Javier Bardem and Tobias Menzies who rose to fame after playing Prince Phillip in the Netflix hit The Crown.
