Chris Hemsworth tweeted a picture of his dramatic weight loss for his upcoming role in Ron Howard's In the Heart of the Sea. It looks like someone stuck a pin in Thor and deflated him. In the Heart of the Sea is based upon the non-fiction novel of the same name, which tells the story of a crew trying to survive after their ship is struck and sunk by a sperm whale, which was actually the real-life inspiration for Herman Mellville's Moby Dick. The movie looks like it will be Cast Away or Life of Pi but set in the 1800s. To portray the starving sailors, the actors of the film went on crazy, 500-calorie-a-day diets. Hemsworth decided to share what that looks like on social media:
