Surprised I'm the first to mention For All Mankind as another great Apollo documentary. It was nominated for an academy award and is really well polished. Brian Eno did an amazing score of ambient music for it too. Don't go in expecting a factual run down of the Apollo era, in fact there's no narration at all and just great clips and bits of actual film from the training, launches, missions, etc. Criterion Collection has a great release of it that's worth a purchase if you're at all interested in space or the Apollo missions.
