Los Angeles: Actor Chris Hemsworth, who gained 20 pounds of muscle to play superhero Thor, is now working on losing weight by going on a crash diet.

The 30-year-old, who will be seen in `Heart of the Sea`, shared back story of why he needs to lose weight for the film.

"A bunch of sailors in a whaling ship get struck by a whale, the ship sinks and they jump onto the small rafts and drift for 90 days. And basically they begin to die and eat each other ... a romantic comedy," quoted Hemsworth as saying.

"And we have to get rather skinny. So we`re on 500 or 600 calories a day,” he added.
