Here's some thoughts on the ISS:
Visit the ISS.
Been looking at videos regarding this and there are cinematographers that say it's a model and there are painted or projected backgrounds according to their analysis but at the moment I can't say. I agree that stars would not be visible on film unless the surface was over exposed. Stars may be able to be found if one had the original still Ektachrome transparencies. Perhaps detailed analysis would reveal stars not visible to the eye. People have been analysing the images available and though they find no stars some curious artifacts are present in some. Things that look like cuts and masking, suggesting edits using early 70s tech.
One thing that stands out about video are the shadows at the beginning of the clip. I now much has been said about the misaligned shadows on the still images but these are moving on video and it looks like there's a second light source at the beginning and end of this 50 second segment. There's only two possible light sources on the moon. Sunshine and Earthshine, doubt it's the latter.
I've taken screen clips and added markers and comments. I've included the times they occur as they appear on You Tube.....

After image 3 the LR heads off in the direction of the LM then returns to it's starting point. Here it is on it's way back, note the shadow directions. This image is for context.

In this image the LR has returned to it's starting point, the video cuts to another scene unrelated to this one after this.

Watch this segment repeatedly at slow speed. I can't see how albedo could account for the lack of shadow where shadows should be. Here's the link again, from NASA's own channel.

I can see where you're coming from, I'm searching for someone who could analyze this to see if it was filmed while in reverse. Will let you know if I find anything. I'm also looking at the still images from NASA's Project Apollo, that's for another post, there's a lot of material to cover. Thanks
