Is that important?
I have, behind me, the entire DVD collection of all Apollo flights to A17.
For Apollo 11, there is indeed a movie taken from the LM, downwards, where the astronauts appear in color and because it's less than 24 frames a second, it's a bit jumpy...It wasn't showing the astronauts all the time (as they walk out of frame) but it looked like it lasted the entire moonwalk duration.
Mark Gray did a great job!
