Yogic diet for Rachel McAdams

Rachel McAdams needed to do lots of yoga to fit into her 'Sherlock Holmes' outfit.

The actress had to wear a lot of tight-fitting corsets for her role as Irene Adler in Guy Ritchie's new movie about the British fictional detective and admits it was a struggle to get them on.

She said: "I wasn't allowed to take that corset off! I had to rely on yoga exercises! Don't get me wrong, I'm such a girly girl, I was in heaven being dressed in these incredible costumes. But it was like something out of 'Gone With The Wind'. I'm holding onto the trailer door trying to eek out just a little bit of space so that I can speak properly. Each morning, they tried to make me laugh and on the laugh they'd yank - that's how they managed to squeeze me in every day."

Rachel also joked she was so desperate to be in the film, she had to beg Guy for her part.

She quipped to Total Film magazine: "I hunted Guy down and camped on his doorstep until he relented! OK, no, we had a chat in a garden and it went from there... Fortunately, it worked out for me."
