Have any famous actors done dubbing work for Hong Kong movies?
Well, not really famous, but a few known actors have done dubbing work. Dwight Schultz (“The A-Team”) did work on “Black Mask”, and Danny Trejo (“Heat”) voiced Sammo Hung in “The Prisoner” (the US version of “Island of Fire”). Even though foreign films in Hong Kong are almost always subtitled, there have been a few instances of HK stars dubbing voices, such as Tony Leung Chiu-Wai and Nicholas Tse doing work on “Cats & Dogs”.
