Great movie, but be forewarned:
The Mask of Fu Manchu is a very enjoyable movie, with one exception.
The acting is great. The pacing and cinematography hold you at the edge of your seat. The special effects are very well done...
...and BOY is this movie racist.
Fu Manchu and his "race" of "yellow people" are depicted, by and large, as corrupt hedonists who despise the white race and want nothing more than to slay the white men and take their white women for their own. They practice human sacrifice, delight in torture, murder without a second thought, and pretty much do everything that 1930s Western society would consider immoral.
It's important to take the movie in context. Racism used to be almost completely pervasive, unlike our more enlightened times when it is socially shunned. It's amazing how far our society has come in just the short time since this movie was made.
If you can put up with the racism, The Mask of Fu Manchu is a very entertaining movie that I highly recommend. 8.5/10
