Sprinkled into the Moon Landing Hoax lore are all sorts of arguments about lighting coming from the wrong angles and producing bizarre shadows, objects moving inconsistently with microgravity, and technical components (including the cameras used to film the landing itself) being impossible to operate from the lunar surface.

The root of hoax theory isn’t merely that it was faked, but that a savvy observer of the footage can identify the Hollywood legerdemain.

CGI wasn’t a thing in 1969.

If you want to get hard-core in your Moon Hoax theories, you’ll inevitably run into people who claim it was.
