“If [Tom] were here, I think what he would be talking about is when I called him up and I basically said to him ‘look, I’ve got good news and I’ve got bad news,’” Nolan began. “The good news is I have a terrific part for you, the bad news is your face is gonna be completely covered for the whole film, so you’re gonna have to get across whatever it is you wanna get across through this character through just your eyes and your voice.
“And what Tom did, which I completely love but it takes audiences time to get used to,” he continued, “is there’s an incredible disjunct between what he’s doing with his voice and what he’s doing with his eyes. His eyes have this extremely threating stillness to them. His voice is this extremely expressive and different voice. And i’ve never really seen anything like it. The first time I ever saw him perform a scene with Christian [Bale], I was shocked by it. I mean I really was like, ‘ok, I’ve just never seen this.’”"
