Reality TV fans have spotted a very familiar face in Furiosa: A Mad Max Saga. 

Mark Whales, 44, who appeared SAS Australia and also took out the championship for 2022 Australian Survivor, has now made it to the big screen alongside Anya Taylor-Joy and Chris Hemsworth.

Eagle-eyed theatre-goers were shocked to spot him in the background acting as 'Brake Man'.

Mark took to social media earlier this month to announced the small gig he picked up in the Hollywood movie.

The father-of-one revealed he first auditioned for the role 'two and a half years ago' and 'never expected I would actually get a call back'.

'I'm not a trained actor, but I've loved film and TV my whole life so I gave it a go,' he explained. 

'I was asked to do a Zoom call with Director George Miller. For an hour he told stories about his time as an emergency doctor in the 1970s and how he had dreamt of a dystopian wasteland.'

The TV veteran, who met his partner Samantha Gash while competing on the first season of Australian Survivor in 2017, went on to say he 'squealed' when he discovered he got the role of Brake Man. 

Fans flocked to his comments to praise the former SAS Australia star, with one pointing out they 'instantly recognised' him on the big screen. 

'Being a Survivor fan I instantly recognised you on screen,' they wrote.

'Saw it opening night, in 4DX. I nearly flew out of my seat. definitely going to see it again. Well done.'

Others said, 'Didn't know that! Well done!' and, 'Fantastic. Congratulations, Mark.'

Another commented: 'This is so good. Well done.'

'Man of many talents, Mark. Your CV just keeps growing in epic ways. You are quite simply amazing!' someone else wrote.

Mark has quite the colourful career under his belt which boasts the publication of a memoir and fiction book, stints on reality TV and a candidacy with the Liberal Party.
