Acting is really instinctual and I think you can overanalyse what you're doing. A lot of it has to be based on instinct.

What I learned is that acting is to a large extent about trying to stave off self-doubt long enough to be natural and real onstage.

There is always this thing of will you get too old for your part? But people are playing a lot younger than they actually are in real life. I don't think it's as big an issue as a lot of people are making it out to be.

I don't think that you necessarily need a certain type of background to take on roles. You see actors from very, very privileged backgrounds playing working class characters and vice-versa. I don't think your background limits you as to what you can do.

My parents are left-wing, and I would describe myself as that. But also, you know what? I wouldn't describe myself as that. Because I don't have to. Because I'm not a political party. Most people are a little bit of each, and we change our mind on various issues.
