Batman was to drop from a plane into the harbor, but the water quality was found to poses a health risk. The South China Morning Post stated, "The plan was for Batman to be seen jumping into the water and then climbing up some bamboo, or something similar. But when they checked a water sample, they found all sorts of things; salmonella and tuberculosis, so it was canceled. Now the action will cut to inside a building."
The Dark Knight is opening July 18th, 2008.
