"There was a funny incident when American air force personnel were invited onto the set and they saw our CRM-114 or whatever it was called, a box of no return. We just came up with something because we had no idea what the real thing looked like, but apparently it was very near to the mark. They went white when they saw all that classified information in the film. I got a memo from Stanley, who hoped I could justify all my research because we could be investigated by the CIA!"
