In the Line of Duty (film series)

In the Line of Duty, sometimes referred to as the Yes Madam series, is a series of girls with guns feature films produced by Hong Kong movie studio D & B Films which star, in the first two, Michelle Yeoh and, in subsequent installments, Cynthia Khan as a Royal Hong Kong Police Force officer who combines use of firearms with Kickboxing. The film Royal Warriors would be exported with the title In the Line of Duty and, due to its success, the film Yes Madam!, released one year prior, was retitled In the Line of Duty II: The Police Assassins as an export. Due to the overwhelming financial achievement of the films under the In the Line of Duty titles, D & B would start utilizing the In the Line of Duty title in their native Hong Kong market, with the third film being the first to originally use the In the Line of Duty name, which in turn would be retroactively applied to the two Michelle Yeoh vehicles. This would continue with the fourth entry before the series would revert to using individual unique titles (though the later sequels would still be exported with the In the Line of Duty naming scheme). ^{[1] [2]}

The official series contains seven movies produced by D & B Films before going defunct after the release of the final entry Sea Wolves. Two other unofficial sequels would be released afterwards in various territories solely for the fact that they starred Cynthia Khan but playing different characters. A 1990 film titled The Queen's High starring Cynthia Khan was marketed in some territories as In the Line of Duty: The Beginning but it is unrelated to the franchise. Out of the official series of seven films, Cynthia Khan playing the character of Inspector Rachel Yeung in parts 3-7 would be the only carry-over from film to film (other than a small supporting character) as there is no plot, narrative or character connection between the first two Michelle Yeoh movies and subsequent Cynthia Khan entries. ^[2]
