The Brides of Fu Manchu is a 1966 British/German Constantin Film co-production adventure crime film based on the fictional Asian villain Fu Manchu, created by Sax Rohmer.
 It was the second film in a series, and was preceded by "The Face of Fu Manchu". "
The Vengeance of Fu Manchu" followed in 1967, "The Blood of Fu Manchu" in 1968, and "The Castle of Fu Manchu" in 1969.
 It was produced by Harry Alan Towers for Hallam Productions.
 Like the first film, it was directed by Don Sharp, and starred Christopher Lee as Fu Manchu.
 Nigel Green was replaced by Douglas Wilmer as Scotland Yard detective Nayland Smith.
Charlie Chan is a fictional character created by Earl Derr Biggers.
 Biggers loosely based Chan on Honolulu, Hawaii detective Chang Apana, and conceived of the benevolent and heroic Chan as an alternative to Yellow Peril stereotypes and villains like Fu Manchu.
 Chan is a detective for the Honolulu police, though many stories feature Chan traveling the world as he investigates mysteries and solves crimes.
Daughter of the Dragon is a 1931 American Pre-Code film directed by Lloyd Corrigan, released by Paramount Pictures, and starring Anna May Wong as Princess Ling Moy, Sessue Hayakawa as Ah Kee, and Warner Oland as Dr. Fu Manchu (for his third and final feature appearance in the role, excluding a gag cameo in "Paramount on Parade").
 The film was made to capitalize on Sax Rohmer's then current book, "The Daughter of Fu Manchu", to which Paramount did not own the rights to adapt.
The Fiendish Plot of Dr. Fu Manchu is a 1980 comedy film, primarily notable as the final film of Peter Sellers, David Tomlinson and John Le Mesurier.

 Peter Sellers handled the re-shoots himself.
 Based on characters created by Sax Rohmer, the film stars Sellers in the dual role of Fu Manchu, a stereotypical Chinese evil genius, and English country gentleman detective Nayland Smith.
 Released only two weeks after Sellers death, the film was a commercial and critical failure.
 It was also the final screen appearance for Tomlinson, who retired from acting shortly before its release.
