I love this film, but . . .
Does anyone believe RKO sent cast and crew to China in 1952 to make this B&W movie? That's what IMDb lists for Filming locations: "Hong Kong" and "Macau." Really? For a story line that takes place mostly indoors? Or, when outdoors, on fairly obvious sets (some in front of what appear to be rear-projection screens)?
Except for opening scenes of a ferry boat approaching Macao (probably stock shots missing the "atmosphere" to match the rest of the movie) this film must surely have been made at RKO in California. Does anyone reading this know?
