Chris Hemsworth shares nightmare of 600-calorie daily diet

Chris Hemsworth stars in Ron Howards In The Heart Of The Sea

One of the most memorable takeaways of making a movie like In The Heart Of The Sea had to be the fact that all actors onboard the recreated whaleship Essex were put through an unimaginable diet.

Ron Howard’s guiding principle while making this film was, after all, to be as authentic as possible. And so if the men were purportedly out at sea for 90 days with nothing more than hardtack (biscuit) and tortoise meat, then by God, they would look like that’s what they had eaten.
