Danny Dyer has revealed he felt humbled working with real Army veterans on his new film Age Of Heroes.
The screen hardman stars alongside Sean Bean in the film, which is based on the true story of James Bond writer Ian Fleming's founding of 30 Commando, the template for today's SAS, and the movie employed former members of the British Armed Forces as extras and stunt men.
Danny revealed: "It was very humbling. You think you're a man's man but you're not until you meet people like that - so much respect for them. Which was why it was important that I tried and did it a bit of justice."
He went on: "Some of the stories they were telling us... there was one guy who had been looking at a map when he was in Afghanistan and a sniper shot him through the hand and there was a hole in his hand and it hit him in the jaw.
"And he was telling me this story, but so matter of fact, and I was just so freaked out by this story, I thought 'Oh my god I'm just some poncy actor trying to pretend to be a commando', and these boys go through it like you wouldn't believe.
"It was great to have them around us on set, and they took the p**s out of me a lot which was quite healthy."
Danny was trained by Marines for the film, but he revealed he didn't get as fit as he'd hoped.
He said: "I would love to have gone on some mad fitness regime, but actually it was more about weapons and just learning a little about the Second World War."
::Age Of Heroes opens in UK cinemas from May 20 and is on DVD and Blu-ray from June 13.
