'Chinese' utterances of Fu Manchu
Has anyone else noticed that from time to time during the film Karloff as Fu Manchu utters some mysterious phrases that seem to bear no earthly relationship whatsover to any Chinese dialect? One happens when he is handed the (ultimately false) mask of Genghis Khan by Terence Granville, but several others are scattered throughout the film.
I wonder if Karloff was just ad libbing there or if the screenwriter actually pencilled in anything at that point.
