As with the moon landing, the spotlights on the soundstage cast a shadow on one half only so the video cameras can make the scene appear more realistic. Stagehand’s dirty t-shirt was shown in left corner at first until they waved him out of the way. Then edited and brought frame in tighter so you can’t see the “exit” sign in the distance. A lot of work to make these almost real.
(Kidding).
You forgot the coke bottle that was crushed by the lunar lander’s landing pad. Neil Armstrong almost tripped on it.
That might be why he forgot his line, “That’s one small step...” Just kidding.
