"The Mask Of Fu Manchu is a typical MGM production, with a headlining star, a name supporting cast, and lavish production values... There is a tendency these days to think of "back then" as a more innocent time; but even a brief examination of the films of the pre-Production Code era should be enough to dispel that misguided notion. The few years between the coming of sound and the crackdown in censorship from 1934 onwards saw the release of numerous films featuring a quite staggering degree of cruelty and perversion... Where The Mask Of Fu Manchu is likely to blindside modern audiences is in the explicit sexual sadism of Fu Manchu's daughter, Fah Lo See." - Liz Kingsley, And You Call Yourself a Scientist!?
