If there's one reason for watching Jay Weidner's documentary above it's for the explanation of front screen projection used in the Apollo missions staged photography. You can also see it clearly in the photo above along with a typical studio light stand from the period, being used on a set that it's very likely Stanley Kubrick directed. The basis for this claim is also explained in the documentary.
To this day NASA refuse to take colour photographs of the moon or point a telescope at the Apollo landing positions and show us sceptics the evidence of the landings such as moon buggy and so forth. It's been over 40 years and nobody has ever gone back either. A good thing to do if you don't want people asking awkward questions.
