Actor Alexander Skarsgard went on a "misery" diet to get in shape for The Legend of Tarzan.

The 39-year-old Swedish actor hopes he doesn’t have to do the same for a sequel, reported Femalefirst.

"It was the misery diet. It was awful. I was on a strict diet and exercise plan for eight months to get in shape. I ate a lot of chicken breasts, it was really hard.

"I got called back to do more filming a few months after wrapping up and I was like, ‘Nooooo’ because I didn’t want to go back on the diet again," Skarsgard said.
