Matte World Digital composited in a full moon sky to create this iconic shot.

MWD generated many backgrounds in this sequence where Catwoman stalks her prey from the rooftops.

As the shot begins, we fly past a bridge to reveal the Hedare factory.

This shot starts as a completely fabricated 3D scene.

Later in the shot we have a better view of the factory, as we look down the cliffline.

The front right corner of the factory was based on footage of an office building where the actors were filmed.

As we drop down into the parking lot, portions of the CG scene change into the plate footage.

The transition is seamless.  Some of the scene remains CG for the duration of the shot.
