The day that I met Christoph Waltz was a very lucky day in my life. We share, just in a collaboration that I think — exquisite would be the only word. He says my dialogue, he sings my dialogue, he sings my dialogue in a way that nobody quite has. His tone, his pitch. He gets it. And just the experience of working with him was wonderful. It was a joy to write the part for him. I didn’t know who Django was, I didn’t know who Calvin Candie was, but I knew who Dr. Schultz was. And it was a joy.
