Undoubtedly the best of the series of Fu Manchu films produced in the late 60s, well cast and well directed by Don Sharp, who commendably eschewed camp ‘Boys Own’ heroics to produce a gripping adventure-thriller. Christopher Lee (as one would expect) is suitably menacing and inscrutable as Fu Manchu, even though the emphasis on his hypnotic eyes is an obvious reference to his role as Dracula. The ever-reliable Nigel Green (Zulu)turns in a solid ‘Holmes-ian’ performance as Fu Manchu’s nemesis Nayland Smith, while James Robertson Justice has a memorable cameo as an irascible museum curator.

The highpoint of the film is undoubtedly the chilling sequence set in a English village, where all the inhabitants have been killed by poisoned gas. It still sends a shiver up the spine. The first sequel, Brides of Fu Manchu, with Douglas Wilmer as Nayland Smith, is watchable, even though it is basically a retread of the first movie, but the films which followed (especially the two directed by the notorious Jess Franco)are absolutely dire.
