Filming in low light was especially important for The Dark Knight Rises because a number of crucial scenes take place underground, including those in the Batcave.
With Wayne Manorand therefore the original Batcavedestroyed in the first film, Bruce Wayne had temporarily moved his base of operations to the Bat-Bunker. However, the mansion was rebuilt with the inclusion of a new Batcave, which echoes design elements of both earlier sets.
Nathan Crowley, who teamed with fellow production designer Kevin Kavanaugh on this film, explains, Chris and I pondered how to mix the Batcave and the Bat-Bunker, which is incredibly geometric and modern and everything is cleanly recessed into the walls. It occurred to us that we could carry over the same idea by flooding the Batcave so everything is hidden underwater. When you enter, its just a cave, but you press a button and up come these perfect cubes that hold different objects, from the Batsuit to a super computer.
Nolan offers, Its a terrific combination of the tactile reality of the Batcave and the functionality of the Bat-Bunker.
The Bat-Bunker was again erected at Cardington. However, the new Batcave set, complete with working waterfalls, was constructed on Stage 30 of Sony Studios in Culver City, California. The soundstage was ideal because it contains a water tank that can hold more than 720,000 gallons of water.
