Kate Bosworth has one blue eye and one hazel eye - a condition known as heterochromia. However, the actress uses this point of difference to her advantage, saying it's actually helped her land certain movie roles. "One of the first things I had to do (when applying for the role of Lois Lane in Superman) was a screentest to see if Bryan Singer wanted to keep (my eyes) the way they are, and he decided that he wanted to. So now the Lois Lane dolls have different colour eyes, which is pretty strange. The doll doesn't really look like me at all, but the eyes are very distinct!"
