So yeah, it was a long, laborious process, but luckily not half as hard as what the astronauts themselves went through.
I had an incredible production designer, Nathan Crowley, who built all of these capsules basically from scratch, as exact replicas of the actual things.
The lights would work, the suits were all functioning — oxygen flowing in, and the cooling tubes.
Well, I certainly underestimated how hard it is to shoot in really, really tiny spaces.
