And, my God, the actors. The cast, led by the extraordinary Jennifer Lawrence, is absolutely wonderful across the board. It’s such a pleasure to see how they’ve embodied the characters and brought them to life."

I can’t have Snow White’s affect on people. I can’t actually be completely selfless because nobody is."

"She’s a very fully formed but very farfetched from the reality that we live in type of person. She also is strong in a very different way than you’d expect like bullying a person in an action-type adventure movie."
