Washington: Keira Knightley found it frustrating that she couldn`t pick up the intricate and elaborate dance routines in the movie ‘Anna Karenina’.

The 27-year-old, who plays the lead role in the Joe Wright-directed film, was all the more upset that her co-star Aaron Taylor-Johnson found them very easy.

“I think I`m quite good at picking things up and I found this impossible and Aaron could just do it in about five seconds. It took a really long time,” a website has quoted her as saying.

However, it was not at all a cakewalk for Aaron, as Joe revealed he was sick during the shooting of the dance scenes.

“One day when Aaron was actually ill, and there`s a bit in the dance when he has a really red face, he was trying not to be sick,” he added.
