"Heath was just so full of ideas and fresh dialogue and so unbelievably fast and inventive. He was still, in some sense, speeding from playing The Joker, which had liberated him in a way that he had never experienced before. He was always telling me 'I am doing things in scenes that I didn't know was inside me. I cannot believe it'."
I'm so excited to see the film when it's released in the UK on 16 October, what about you?
