KV41: Underwater Caverns.
Stage 1 houses the craggy set that represents the "Underwater Caves" of Utapau, as described in the production notes. In truth, the caves are above the surface of the water, in the dark grotto that lines the depths of Pau City's massive sinkhole. The sinkhole cuts off the angled rays of the sun, so that the lower sections of the pit experience night as the upper levels still enjoy daylight. As a result, this set is dark, making the cave a perfect hiding place for Obi-Wan Kenobi in scene 120, shot on Friday, September 5th, 2003, the 50th day of shooting.
