Dan Stevens is unrecognisable from his days as Matthew Crawley in Downton Abbey.
The actor, who left the show at Christmas, looks like he's been on a serious LA-detox since launching his career in Hollywood.
Dan arrived at the London premiere for his big-screen debut Summer In February last night, looking half the man he once was.
The 30-year-old walked the red carpet in a slim-fitting shiny grey Rake suit with a black tie and shoes.
He now has black hair - which he debuted earlier this year - and rather protruding cheekbones.
Though he’s never been overweight, Dan has admitted that he's shed two stone since January.
He revealed on Graham Norton's chat show: "I've lost about 30lbs since New Year, which, in British terms, is about two to three chins.
"It was for a role. It’s always me, just different incarnations, different roles, different costumes and different sizes."
And he added about his new hair: "It’s pretty much my natural colour. I went very dark for the last role but I’ll see where I go with it."
Dan was joined at the premiere by his wife of four years, Susie Hariet, 37, who's the mother of his two children Willow, three, and 13-month-old Aubrey.
The actor's departure from Downton last year was met with anger from fans when Matthew was killed off in a car accident, just hours after his son had been born.
Viewers complained the storyline was more fitting to an EastEnders Christmas special, but creator Julian Fellowes has since claimed it was the only credible option for writing Dan out of the script.
Dan had made it clear he wanted to leave to pursue a career across the pond and Julian wanted to make his exit believable.
Julian said: "If Dan had been prepared to come back for maybe two or three episodes in a series, that would be different.
"Then we could have had a foreign posting or invented a career that would have made it possible for him to be away.
"Otherwise we would have had to make this tremendously successful love affair between Mary and Matthew unhappy, which I didn’t feel would be believable.
"For them to then separate and Matthew never set eyes on his son again would not be believable either.
"So we didn’t really have any option. By him dying, their love can remain in tact."
