The BFI has posted this to their YouTube site. It's the fifth of six installments of of the "Doctor Sin Fang" serial, a knock-off of Fu Manchu that used many of the same actors that the name brand did -- presumably it was cheaper because they didn't have to pay royalties to Sax Rohmer.In this one, the evil Dr. Sin is looking for the Sacred Seal while the good guys are looking for him. There is much skulking around a country home filled with mummy cases that open to reveal sinister orientals, and torture devices that look more annoying than torturous, but unlike most American serials, this one tells a complete story in itself. There's also the continuation of the tradition of serial heroines who actually do something; Evelyn Arden, as the girl friend of star/director Fred Paul does some sleuthing and handles a gun very well.It;s all evil Orientals and stalwart Britons, which is what you;'d expect with this sort of movie. Still, if that's what you're in the mood for, it's pretty good!
