Richard Kiel was most well-known as metal-mouthed James Bond villain Jaws. An obvious reference to the 1975 horror/thriller film of the same name, Jaws gets his name both from his enormous size and strong stainless steel teeth that could bite through virtually anything. His appearances in The Spy Who Loved Me and Moonraker saw Jaws become a legendary character in the Bond mythology.
The stainless steel teeth that Kiel wore when he played Jaws were particularly unpleasant. Kiel could only wear them for a minute or two and would remove them as soon as every shot was finished, because the sensation on the roof of his mouth caused him to gag. In fact, one crew member was specifically in charge of washing and rinsing the prop in a tupperware at the end of every scene. The teeth would be locked in a safe every night during shooting.
With teeth that could bite through almost anything… I wonder how Jaws would have got on with our Stainless Steel Tables!
