I love not having to rely on anyone.

When you're a young actor, there's this pressure to rush. But I hope to be doing this into my sixties and seventies, so I'd prefer to take my time.

There's so much of a desire in the entertainment industry for newness, a desire to build somebody up and then treat them as old news within six months. I think you'd be naive if you didn't try to hold on to your own way of doing things.

I think Nelly [Ternan] actually has something very conservative about her, and she's very judgmental of (this other character's) situation, and can see that's about to happen to herself. So she judges it even more harshly [because] it's what she fears becoming.
