Christoph [Waltz] is stunning, an insanely nice guy. He is not only a ridiculously good actor, he is also really funny, helpful, and a good colleague. I like his work ethic. I mean, the guy has won an Oscar—and despite that he is receptive, open-minded, and not the least bit snooty. And Reese Witherspoon is the same. It may be the nicest cast that I have worked with yet—a really great experience.
