"There’s more daylight as the series goes on. I’ll claim that the reason there’s more daylight is that Chris hates shooting at night. We were shooting nights going into Batman Begins, but we ended up filming an enormous amount of night exteriors inside during the day on sets that we built on a stage in Cardington. It was always a challenge having this character that only comes out at night, and having to deal with that in terms of shooting time and how you use it. We started asking ourselves, well, why does that have to be the case? Chris actually found dramatic ways and reasons to have daylight. One of the scenes that turned it around on Dark Knight was the interrogation, with Heath Ledger, which starts in a dark room, but then we flip on the light switch. Basically at that point Chris was very comfortable with the way Batman looked, and I said, well, what about if I create an environment that’s almost over exposed? Really, really bright. Chris loved that idea, of Batman switching on a light switch and then he starts to kick ass. I think that was the first time we really explored a brighter environment for Batman."
