I didn’t shoot it like a scene where you [say] action [and] cut. I kind of let the camera roll for four or five minutes and I let Helena and Emma improvise to a certain extent those moments, so they could build an intensity together. […] There were one or two moments that were really powerful, where Emma was able to just let go a little bit and forget for a moment that she was acting. And the screams were quite horrible to listen to. It was a very odd energy in the room. I felt in that moment, and in that day and in that room, she kind of crossed the line as an actress. She discovered something within herself that will make her a great actor. (x)
