"The scene starts between Gary Oldman [as James Gordon] and Heath with the lights out, and [director of photography] Wally Pfister literally just lit the scene with the desk lamp, the table lamp, and nothing else. And then when the lights come on, Batman is revealed, and the rest of the scene plays out with a massive overexposure. He overexposed like five stops, I want to say, and then printed it down to bring some of the color back in. But it’s this incredibly intense overhead light which let us move in any direction. We had a handheld camera and shot however we wanted, be very spontaneous.
For me creatively, that had been about inverting the expectation. We’ve all seen so many of these dark movie interrogation scenes where somebody is being given the third degree. We just wanted to completely flip that on its head. And have the bright, harsh, bleak light sort show you the Joker’s make-up and its decay. The Batsuit was redesigned for this film. And unlike the suit that we had in Batman Begins, it’s capable of really being shown in incredible detail and still hold up to that kind of scrutiny under that bright light. The suit looked much more real and more like a functional thing this time. The whole scene was about showing something real and brutal and getting this real harshness.”
