New image reveals Chris Hemsworth’s dramatic weight loss

Chris Hemsworth has slimmed down quite considerably to play a 19th-century stranded sailor for In the Heart of the Sea. He revealed the incredible and scary transformation on twitter…

Hemsworth told EW earlier this summer about the grueling effort that went in to losing so much weight. “When you’re already starting off lean, its brutal to chew through that kind of weight,” Hemsworth said. “Every pound feels like a kilogram.”

Hemsworth stars as real-life first mate Owen Chase, who served on the whaling ship Essex and was stranded at sea after a whale destroyed the ship. To play men cast adrift with no food, Hemsworth and his co-stars reduced their diets to a measly 500 calories a day.

“They had to work out every day, even on shooting days,” director Ron Howard told EW. “Because they had to lose the weight pretty fast and they had to lose it safely. They needed to keep burning the calories and we also needed that sinewy strength that was more of that era, as opposed to a kind of cut, buff look.”

In the Heart of the Sea hits screens on December 11th.
