Supposedly a franchise killer due to the usual politically motivated, force fed thematic suspects.
Rumor is that all of the traditional Bond movies reflected some real world incidents. I never saw OHMSS, but watched it recently on You Tube. It was pretty good. It sounded like Lazenby's voice over was done by Connery in his swan song nod although I never heard about that happening. Did Lazenby have a high, squeaky voice or something? I was waiting for him to choke or beat somebody to death with his vaselined toupee. Diana Rigg was so YOUNG.
OHMSS was the one reflecting current events most closely I heard. Insane Swiss redoubt manufacturing deadly virus to unleash on the world in a power extortion grab, but methinks any other clarifications might wander into poly ticks.
