Jim Sturgess reveals desert diet
Jim Sturgess has revealed he went on a diet to play an escaped prisoner in The Way Back.
The 29-year-old actor stars alongside Colin Farrell, Saoirse Ronan and Ed Harris in Peter Weir's new film about soldiers who escaped from a Siberian gulag in 1940, which saw them shooting their long trek to freedom on location in snow and the desert.
Jim said: "I didn't starve myself but I definitely put myself on a diet. I wanted to see what if felt like to go for an entire day, which I don't think I've ever done before, without eating anything.
"Just to see what kind of cramps you get, whatever that feels like. But I don't think I starved myself. Maybe for one day."
But Jim admitted filming in the Sahara Desert meant he wasn't very hungry anyway.
He revealed: "The pure nature of being out in the desert didn't make you want to eat anyway really - when you're in the middle of the Sahara Desert out in the baking heat.
"You'd go in the lunch queue for food and there'd be flies all over the lamb or whatever and you'd be like 'I think I'll just have a bit of rice or a bit of bread'."
