"Lizzy, who I trust immensely, went away, and it was almost like a stunt rehearsal. I would be doing dance sequence in the room next door, they would be doing an intimacy rehearsal. Lizzy would say, ‘Hey we are ready, we’ve got something to show you’. I would go in, I would look at what they did, and I would be specific about changes that I wanted just in the same way as I would be with a fight sequence and a stunt coordinator.”
