Diaz would do anything for her loved ones

Cameron Diaz found it easy to empathise with her 'My Sister's Keeper' character Sara Fitzgerald, whose daughter has terminal cancer, even though she isn't a mother herself.

She said: "I think we all related to the fact that there isn't anything that you wouldn't give someone that you love that deeply. You do whatever it takes to keep that person alive. I think that that's something that spoke to most of us, for this film, and what I think is so effective in the film."
