Yes, Mada (1985)
Directed by Corey Yuen
Yes, Madam (皇家师姐) is a 1985 Hong Kong action film directed by Corey Yuen and starring Michelle Yeoh and Cynthia Rothrock.
The film also features appearances from Dick Wei, Tsui Hark and the film's producer, Sammo Hung in a small role.
The basic plot revolves around a small microfilm containing details of a group of villains involved in illegal activities. The microfilm is in the possession of some petty thieves, whilst the police are looking for it to prove the villains guilt, the villains want it destroyed.
Yes, Madam or Yes, Madam! is also known by several alternative titles including:
Police Assassins (UK title for DVD release)
In 1987, Cynthia Khan took on the lead role of female cop in the film In the Line of Duty 3, which was also known by the title Yes, Madam 2.
Also in 1987, Yeoh appeared in the film Magnificent Warriors which had the alternative title Yes, Madam 3. This would be the end of Yeoh's involvement with the series.
In 1989, In the Line of Duty 4 was released, directed by Yuen Woo-ping and starring Cynthia Khan alongside Donnie Yen. UK and US distributors added further to the confusion by dropping the "4", releasing it as In the Line of Duty. It was also known by the title Yes, Madam 4.
The one constant in all of the subsequent films was Khan, and further title cross-overs occurred in this vein. In 1995, Khan appeared in a completely new and un-related film with the title Yes, Madam!. In 1996, she appeared in In the Line of Fire III, which was also known as Supercops, Police Assassins 2 and 'Yes, Madam 5 amongst other titles.
Finally, Michelle Yeoh also appeared in the Jackie Chan film Police Story 3 (aka Super Cop), and the semi-sequel / spinoff Once a Cop, which was also known as Super Cop, Super Cop 2 and various other titles.
