He will be back!

Arnold Schwarzenegger has confirmed he has started working on the sixth installment of the Terminator franchise.

Directed by Tim Miller, Schwarzenegger will reunite with James Cameron who has signed onto produce the film. Cameron had previously worked on the first and second Terminator films.

The world's most famous body builder confirmed the news via a video message to the Fiji Prime Minster, Frank Baninimarama - who was speaking at the Climate Action Pacific Partnership conference.

The actor said "I’m sorry I cannot be with you but I’m currently shooting Terminator 6 and so this is why I’m not there".

With Linda Hamilton also set to return to the franchise, the new movie will have a fresh and unique storyline that brings the movies back to their roots.

"I think Cameron and Miller came up with a concept where they can continue on with the T-800 but make a whole new movie," Schwarzenegger said. "What they are doing now with this one is basically to just take a few very basic characters, like Linda Hamilton’s character and my character, and dismiss everything else. Just move away from all these rules of the timeline and other characters."

The film is due to be released November 22, 2019.
