"Snow Cake is a lovely film. Really proud of that. We shot it in 21 days. I thought Sigourney was amazing in it. And very, very accurate. I think there was some element that thought she had pushed it too far. But not at all when you do the amount of homework she had done and spent the amount of time she did with adult autistics. She was right on the money. And I think Marc Evans is a terrific director. He's a sweet, open, honest man and a really good director of actors."
