What are the best documentary movies about the race into space?

this one isn’t so much about the race into space but its about Americans going into space called “a funny thing happened on the way to the moon” a very interesting documentary.

I have a pretty good one called “NASA: 50 Years of Space Exploration.” It’s 5 dvds, mostly of archival launch, mission control, space footage, etc. that’s voiced over, ranging from the early, Vanguard and Explorer days until the present. I’m not sure if it truly fits into the category of “documentary,” and there is little about the Soviet side of the space race. Still a good deal though…I picked up the set for $15 at best buy a while back.
