QUESTIONS

Q: I have strong memories of a science fiction film or series of the Fifties in which the hero and villain face each other around a circular table that has six nozzles. Five produce a harmless puff of smoke, but the sixth hides a deadly laser. The table rotates each turn, so the adversaries play a futuristic Russian roulette. Does anyone know what it was?
