Chris Hemsworth says he lost around 15 pounds in the course of shooting the historical seafaring epic 'In the Heart of the Sea.' That may not seem like a huge amount when compared to say the 60-or-so pounds Christian Bale famously made disappear for 2004’s The Machinist, but Hemsworth had already trimmed down to star in the thriller Black Hat, which he had shot immediately before.
“When you’re already starting off lean, it’s brutal to chew through that kind of weight. Every pound feels like a kilogram.,” he said.
In the based-on-real events film, Hemsworth plays a 19th-century seaman called Owen Chase, first mate of whaling ship the Essex. After a whale destroys their ship, Chase and the rest of the crew have to survive the elements, and lack of food, in tiny, lifeboat-sized craft.
To convincingly depict starving men, the cast members’ diets were steadily reduced over the course of the production. By the time they began to shoot on the open sea around the Canary Islands, the actors were consuming just 500 calories a day.
“We kind of went insane, weighing ourselves every day,” says Hemsworth. “We all felt like a bunch of supermodels, trying to get down in weight for a show, or something. That’s all we spoke about. You’ve got 15 burly blokes on the sea and all we talked about was our diet, and who’d lost more weight, and who’s looking really skinny. It’s ridiculous!”
