I did all sorts of jobs after drama school - working in a bar, as a teaching assistant. I probably learned as much from them as I did at drama school.

As actors, you play people who are not yourselves!

I certainly never saw myself as posh.

Playing a plainer role means everything is dependent on the credentials of the actor, not the fact that they are as pretty as Julia Roberts. People start to look at their talent rather than their appearance. And playing the ugly part often means less time in the make-up chair, which is a great benefit on set.

When I'm in a tricky situation I often think: 'What would Beyonce do?' It helps.

I don't really get recognised very much.

My history teacher was utterly terrifying, but her lessons were very inspiring. She got me interested in people and stories, which then led me to acting.
