How did she do that?
She was just so relaxed about it, I couldn't help but be relaxed, too. I did get very, very giggly. There were points where I was laughing because it seemed so surreal. There is actually one moment in the scene where she kisses me, when Roger left the camera on me just a beat too long, and I started cracking up because that was the first time I had been kissed on-screen, in front of a crew. Totally out of character at that moment, because I thought he'd cut the camera. But actually it worked really well in the context of the scene.

So you finished December Boys nearly two years ago. Why the hold-up releasing it?
I don't know the conversations exactly, but obviously, these things need to be spaced out, because I don't want it to cloy. People have been seeing a lot of me this year. December Boys is an independent film, and it takes a while to get the distribution together. It's not going to be playing on masses of screens at all. It's not like Potter. The publicity we do for Potter is great fun and all of that, but ultimately, Harry Potter, people will go and see it.

They're predisposed to see it, really.
Whereas with December Boys, every interview counts.
