Which film? There's tons of still and moving imagery that's all publicly available for scrutiny and that I haven't seen any real criticism of. Did they have After Effects in 1969?

How do you explain all of the footage? How do you explain the laser ranging data still being produced to this day using the reflectors left on the moon by the Apollo missions?

It hasn't been reproduced because the space race was won and the cold war ended. It's incredibly expensive to go to the moon, I think the US used something like 1% of its federal budget on it. Even back in the 60s, during the height of the cold war and "red moon" panic, there was a lot of pushback from taxpayers. There have been various proposals to go back in the past few decades but there just hasn't been the budget. As I'm sure you're aware the Artemis program is now in full swing and we'll likely see another moon landing before the end of this decade.

Computing power isn't the limiting factor. And especially not the on-board computing power; the calculation-intensive orbital mechanics was all done from the ground using the many rooms full of computing power at nasa, not the AGC on board. All of the source code is public and there are simulators/emulators out there so there's no excuse for not understanding how it was done and how everything was programmed.
