Factual error: When Chris and Jackie are stripped butt naked at the freeway, they were in Causeway Bay (on Hong Kong Island). It is impossible for them to go back to the Yau Ma Tei Police Station in Kowloon Peninsula. The only way to get there is by traveling through tunnels or using the ferry. There is no road that you can walk along.
Factual error: After the first shot of Carter as he is walking up the stairs of the building with the bamboo scaffolding, the New York Life Building is in the background. This scene is supposed to take place in China. (Scenes were actually shot in Hong Kong, China, but the NY Life Building has famous distinctive architecture.)
