Christopher Nolan on the art of the reaction shot

Jordan Goldberg: In closing, what would you guys say you’ve learned through this experience?

Christopher Nolan: I’ve learned to get more reaction shots. [All laugh.] I’ve learned you can never have too many reaction shots to something extraordinary. Just on a technical level. In order to portray an extraordinary figure in an ordinary world, you have to really invest in the reality of the ordinary and in the reactions of people to him. That, to me, was what was fun about taking on this character because it hadn’t been done before. He is such an extraordinary figure, but if you can believe in the world he’s in, you can really enjoy that extraordinariness and that theatricality.
