Brad Pitt took inspiration from his Once Upon A Time alter-ego at the San Sebastian Film Festival on Wednesday.

The actor, 62, bore a striking resemblance to his character Cliff Booth as he rocked double denim, sunglasses and tan suede shoes to the photocall of his latest film, Heart Of The Beast.

Brad appeared in high spirits as he waved to fans before he did a Q and A about the film. 

In his new film, Brad stars as retired Special Forces officer James Belmont, who is accompanied by his retired combat dog Odin when their plane crashes in the remote Alaskan wilderness. 

The two survive the crash, but they're forced to fight for survival in bitter conditions while hoping to be rescued.

Brad's nod to double denim comes ahead of his Once Upon A Time In Hollywood sequel. 

Once Upon A Time In Hollywood, released in 2019, starred Pitt as Cliff, a stuntman for Rick Dalton (Leonardo DiCaprio).

Director Quentin Tarantino previously fleshed out the character beyond how he's portrayed in the film with a novelisation of Once Upon A Time In Hollywood that he wrote. 

While the upcoming film will focus on Cliff, Brad clarified  that the project was 'not really a sequel but an episode' featuring the character. 

'This is something Quentin Tarantino wrote. It’s an episode, not really a sequel, but an episode of the character from Once Upon A Time,' he told Deadline. 

The Further Mis-Adventures of Cliff Booth is scheduled to release in IMAX theaters globally on Wednesday, November 25.

Brad was mobbed by fans when he arrived at the festival – just after friends revealed how his marriage to Angelina Jolie sent his life 'spiraling'. 

A source close to Brad said: 'He never had a drink problem, he had an Angelina problem. He's worked hard on himself and he's now, finally, in a really good place.'

Brad and Angelina, 51, split back in September 2016 following just two years of marriage.

It comes after in an interview with L'Officiel USA published on September 9, Angelina stated that she's ready to leave the United States and 'be a bit nomadic' now that her two youngest children, twins Vivienne and Knox, have turned 18.
