Meanwhile, back in the old aircraft hanger where they staged the moon landings ...
Yeah, this is a good one. Funny photos. Exploding spacecraft (they really did, prototype rocket engines kept blowing up test pads, took ages to get right). Having to pass through radiation belts. 2001 was in cinemas Xmas 1968, leaving 6 months for film techniclans to prepare for "the next one" ...
But, to keep constant contact with Apollo crafts, Nasa needed huge network of radio dishes (cos earth spins, very inconvenient!). There were maybe 7 or 8 places around the world "hooked in" (film The Dish), and some special NASA ships at sea too (not many radio telescopes mid-ocean!). People at all these places detected the radio signals coming direct from the spacecraft(s).
There's no doubt Apollo rockets went to the moon. If they were really unmanned, NASA would have had to fake both constant voice coms and telemety (remember Apollo 13?), and some TV stuff, and beam it all up to the real spacecraft(s), to transmit it back, in order to fool all the people receiving it.
(Added), don't forget, the spacecraft transmitted TV much of the time - not just during "public" broadcasts - which was seen in many places. How could the astronauts "simulate" weightlessness for so long, continously (in some cases, 2 weeks)?
(Added) After watching the excellent "Apollo" on Sound TV, seems it was actually 14 receiving sites, which greatly strengthens this argument!
