Kids should be naughty and go through that rebellious phase I didn't have.

Hollywood 'friends' are only after one thing. They're looking out for the next big thing, and they don't want to miss out on you just in case.

I'm afraid that what most people don't know about me is that I'm very close to my brother and sister, who are 16 and 13, and I think I'm a pretty good big sister to them.

I just feel incredibly lucky. I went to drama school and about 28 of us graduated. I graduated from drama school in 2000, and I would say about two of us are working and able to make a living out of it. It is a tough profession. To have the kind of success I have had is really amazing, and I am incredibly grateful.

For some reason I just lack that ability to be embarrassed about going up to people. I even do it for friends if they want to ask someone out.

Mom's a writer, so I grew up reading scripts and I have a real respect for them and I know how much thought goes into creating a role, so I'm always interested to find out what was the thought process of the writer and how best can I convey it rather than trying to change it to suit myself.

I can't impersonate someone. That is not what I do. I can only take someone's essence and create a character out of that.
