It's the Bond movie written by Roald Dahl, and once you know that, it all makes sense. It's ridiculously silly, full of trap doors, mini-copters, ninjas, and bad Japanese "disguises." Connery is treading water at this point, easily overwhelmed by Donald Pleasance in their scene together. Still, with Connery it's never all bad, and if you can let yourself relax into the more light-hearted atmosphere it can be very enjoyable. Great song, too!
