Chris Hemsworth survived on 500 calories a day while shooting 'In the Heart of the Sea'.
The Australian actor, who recently wrapped shooting the upcoming disaster film directed by Ron Howard, embarked on an extreme diet for “three or four weeks” in a bid to slim down to play shipwrecked sailor Owen Chase.
Speaking on the set, the 32-year-old star said: “We have to shoot the really skinny stuff where we drop down to 5, 6, 700 calories a day, a good three or four weeks and it's going to be pretty uncomfortable, but we'll be together in our misery.”
While Chris was happy to transform his body for the role, he admitted giving up his favourite food, including “all the bad stuff, burgers, chocolate, ice-cream,” is never easy.
He told 'Entertainment Tonight': “Anything that is not on the menu is automatically something that you have an absolute obsession with. I spend more time thinking about food than anything else at the moment.”
Ron got tips from his close friend Tom Hanks, who has lost a dramatic amount of weight for roles in the past, including 'Cast Away,' on the healthiest way to get the cast to lose weight.
The filmmaker said: “He gave me some good clues and he also said you know, 'make sure it's organised, it's healthy.' “
In between starving and bulking up for roles, Chris has discovered that his daughter “doesn't like” his Thor costume.
The 'Avengers: Age of Utron' star's little girl India Rose, two, used to like being swung around when he bulked up to portray the superhero, but now she doesn't like his outfit or accompanying long blond wig.
Chris - who also has twins Sasha and Tristan, 16 months, with wife Elsa Pataky - said: “My daughter, with the Thor costume especially, used to be like, 'Oh yeah, it's a big different' and she was happy that I'd pick her up and swing her around.
“Now, she's like, 'Off, off' because it's all bulky and metal, and she pulls at the wig, she doesn't like the look.”
The 31-year-old actor admits he doesn't speak his wife's native Spanish as well as he'd like but knows he needs to up his game before his kids' linguistic skills outdo his own.
He said: “Our daughter is already speaking Spanish and our twins are going to be fluent in bother English and Spanish. Maybe I'm going to have to raise my Spanish level.”
However, the 'Snow White and the Huntsman' star does have one very important phrase mastered.
Speaking to Sorted magazine, he laughed: “I've learnt a very important Spanish phrase which helps calm things down - Si, mi amor (yes, my love).
“Saying 'Si, mi amor' is enough to cool things down between us when we're having one of those typical husband-wife moments.”
