Thor star Chris Hemsworth a shocking shadow of his former self as weight plummets for new role
Chris Hemsworth has undergone a remarkable physical transformation in the name of his latest film role.
The Avengers star shared a picture of himself revealing his unkempt and emaciated new look.
"Just tried a new diet/training programme called Lost At Sea," he wrote on Twitter. "Wouldn't recommend it ..."
Hemsworth was referring to the forthcoming Ron Howard nautical adventure In the Heart of the Sea.
The film, in which a whaling ship is wrecked and the crew are forced to resort to cannibalism, was shot in late 2013, but will be released this December.
Alongside co-stars Cillian Murphy and Ben Whishaw, Hemsworth was placed on a 500-calorie-a-day diet to convincingly portray the experience of a starving 19th century seafarer.
That's only 20pc of the recommended daily intake for an average man in the 21st century.
"I spend more time thinking about food than anything else," Hemsworth said during the gruelling process.
"We have to shoot the really skinny stuff where we drop down to 5, 6, 700 calories a day, for a good three or four weeks and it's going to be pretty uncomfortable, but we'll be together in our misery."
The actor, who had already shed much of his Thor bulk for Michael Mann hacking thriller Blackhat, revealed losing yet more weight had been a tough ask.
"When you're already starting off lean, it's brutal to chew through that kind of weight," said Hemsworth, who plays first mate Owen Chase in the movie.
"Every pound feels like a kilogram."
