I watched the simply titled "Apollo 11" documentary released last year. It is remarkable for making use of a lot of previously unused 70mm film footage taken at the time- although obviously not on the space capsule itself. The quality of the footage really is astonishing and makes the events feel very immediate. I also appreciated that there was no narrator so you are carried through by announcements to those watching the launch (and there is a few minutes of footage of the crowds camped out to do that) dialogue between Houston and the crew, etc. Just the scene of the rocket moving up to the launch pad on those massive tracks was phenomenal.
