"We had some really dark laughs"

How difficult was it playing a real person on film?
I think I was sort of naïve about playing Harper Lee initially because I wasn’t probably as fearful as I should have been because there’s not a lot of public record of her. Phil had it worse because he had so much imitative stuff to do as well as the soul of the performance – which he did accomplish beautifully. For me, I played a woman who’s still alive and who I respect greatly and I don’t know anything about her. I don’t know what she sounds like and there’s very little written about her. I did happen onto a couple of essays that she wrote which informed me a lot and they outlined the important things to her – compassion, love, morality and justice. So I wasn’t trying to do an impression of somebody because there wasn’t anything to really model it on.

Did you research the relationship between Harper and Truman Capote?
Well, there’s correspondence between them and you do know that when she wrote To Kill A Mockingbird, she based the character of Del, the next door neighbour on Truman – they were friends from childhood.
