...presence of Bikini Atoll in photos taken during the inevitable overflights to verify the story by high-altitude Reich supersonic spy planes. Or lack of any corroboration whatsoever from any Reich intelligence service.

Yeah, I had to avoid looking at that one too closely. Seemed too thin a deception for holding off a nuclear war.

But ya know, the film wasn't the thing that actually brought down Heusman, it was the dossier Smith brought with him and presented to the Reichsmarshall. So maybe the deception with the film only had to last long enough to get Smith access to the general? After that, given how close they came to nuclear war, no doubt everybody involved would just rather forget about the whole thing, film included. Maybe.
