Black Dragons with Bela Lagosi as a Nazi plastic surgeon.
Aside from the fact that Karloff doesn't look Asian, Doomed To Die is somewhat interesting. Its a mix between a comedy & a mystery and it really keeps you guessing till the end. I wont go as far as to say its a good movie (after all it is a William Nigh film) but it isn't awful either. Worth a watch for Karloff fans who can dig old time mysteries.
