Benedict Cumberbatch has revealed how he ate lots of chicken in his attempt to shape up for Star Trek Into Darkness.
For the physically demanding role, the Sherlock star had to go on a strict exercise routine and change his diet to include more protein.
"I didn't go the junk food way. I love the chicken, all sorts of chicken, salmon and protein shakes. For two weeks I was just eating chicken, potatoes and broccoli," he said.
Cumberbatch decided to hire a dietitian when he got jealous of his Star Trek co-stars.
"I suddenly discovered they were all walking on set with these beautiful bags of pre-made meals, that had been put together by dietitians. So I got one so I wouldn't have to eat chicken, chicken and more chicken," he recalled.
The 36-year-old admitted that getting in shape to play terrorist John Harrison in JJ Abrams' sci-fi sequel was hard work, and a far cry from the other parts he usually plays, but he relished every moment of it.
"I loved all that. The amount of live action this man JJ lets us do and wants us to do is part of the visual thrill," he said.
"I've never been asked to before, and it was integral to the character, who had to have a strong physical shape and presence and be able to move at the same time so I had to be able to stretch and fling my arms and legs about a bit."
Chris Pine, Zachary Quinto, Zoe Saldana and Simon Pegg also star in Star Trek Into Darkness, which is in cinemas now.
