This is a very silly, racist film, but also a stylish one, and Karloff and Loy--in her early exotic phase--are appropriately creepy.

Schlocky fun, but even Karloff can't make it more than that. The silly racism gets tiresome, and the acting outside Karloff and Loy is mediocre at best.

Evidently the Chinese of all people (rather, orientalist stereotypes thereof) are interested in bringing Ghengis Khan back to life - in order to "wipe out your whole accursed white race" no less. It's hard to decide whether a movie like this is charmingly naive or inexcusably silly. With the riveting Karloff as the "hideous yellow monster" Fu Manchu, and quite endearingly quaint effects and art design, one does lament that the text and rest of the cast are not just a little bit more intelligent.

An especially enjoyable pulp crime with Myrna Loy giving a surprisingly lurid performance as a sadist.

Faithful to the spirit of the Sax Rohmer novels, and in many ways better than most of them, with some genuinely creepy cliffhanger moments. Karloff is sadly wasted in the title role, but Myrna Loy generates some intrigue in what must have been one of her most thankless roles.
