Many actors have transformed their bodies over the years for a series of grueling, hard-hitting roles, with the likes of Christian Bale and Matthew McConaughey known for doing this on more than one occasion.
However, not many people could have guessed that the British actor Simon Pegg of Paul and Mission Impossible fame would buff up for a role.
In an incredible transformation, personal trainer Nick Lower posted a photo on social media showing off Pegg's shredded new frame which he described as 'lean, VERY lean.'
The gruelling gym work is for his upcoming role in the indie movie Inheritance.
"It required a specific body shape and look," Lower added in the tweet.
Pegg's body weight is thought to have gone down from 78kg down to an impressive 69kg, with his body fat at just eight percent.
For those interested in getting a full-on six-pack like Pegg's, Lower said that it was the result of 'a mix of strength, circuits, core & 60km p/w trail runs!' and 'a sound nutrition plan that worked for him and his goals'.
Hacks at the Hollywood Reporter have described Inheritance as a movie which chronicles the family of a wealthy patriarch coming to terms with a family member's death only to uncover a life-changing but unexpected inheritance that will change life as they know it.
Talking to SlashFilm, Pegg revealed that it was the gripping dialogue that persuaded him to take on the project. "It was nice to see some really, really chewy dialogue that was twisted, and a bit strange and felt like a little dinner theatre play that you might see somewhere, and that's what really drew me to it.
"Also, the fact that it was a group of young people making their first feature. They pulled themselves up by their boot straps, called themselves producers, and have their secret weapon in Margot as well which gave it some momentum. That really appealed to me."
The film also stars the Aussie actress Margot Robbie, who Pegg said was a great actor to work with.
"Margot and I just got in the room and started kicking around our own motivations with Vaughn, who's also the writer and the director. Which is great because we were able to say, 'Hang on, I think this might be a little too much at this point', or, 'Maybe Annie doesn't feel this way about him at this point'.
"Being able to get to set with all those problems solved was great, it meant that we could work faster. Which, on a 27-day shoot, whatever it was, you need to do."
