The first film ("The Mysterious Dr. Fu Manchu") was barely watchable, and this follow-up is not much better. It's about 90% talk and 10% action. Warner Oland has screen charisma but his arch-nemesis, O.P. Heggie (playing Inspector Smith) has almost none, so their supposedly grand "battle of wits" is mostly just a tedious exchange of words. But the last 2 minutes ARE reasonably exciting - if you make it that far. *1/2 out of 4.
