Il gioiello di Khama

Eccentric American millionaire Aurelio Sidney hires poor painter Aurelio Sidney to be his double for a week, live in his house, and get $100,000 thereby, because he looks just like the millionaire, because they are played by the same actor.

Don't do it, Aurelio! There's your girlfriend, and his girlfriend, and a band of angry Indian cultists out to burn you ... I mean Aurelio, the other one to death, because he's stolen the sacred jewel of their god, and they must get vengeance within a year, because...well, it adds a certain immediacy to the proceedings, I suppose.

Yes, it's the old Stolen-the-jewel-from-the-Indian-temple plot, something which I have not seen done straight since Arthur Conan Doyle tried a variation on it in THE SIGN OF THE FOUR. It's handled in such an episodic manner that I suspect this was originally a serial. However, given the rising level of threat until someone does something obvious about the turbaned maniacs running around the estate, it's a nice arc, and the ladies get to do something intelligent occasionally. I suppose it all comes down to the question of whether you're willing to accept the basic plot. If you are, then it's pretty good. Me, I'm not.
