I've been passing "Fabrication of the Accelerator Structure" (the un-remastered version) around to people the last several years to show some people where I work.

Andy recently remastered these. I hadn't seen the first one before, but the second one is 100% work 42 minutes of your time. The narration is great, the topic is great, the pictures are great. Unlike current videos, it's happy to dwell on shots for more than 2 seconds, in silence, while people are actually working - instead of the pretend-working for a camera shot with dialog or futuristic music to fill the silence.

I really wish they'd have created more of these types of videos over the years, but $84k in today's dollars for a video would be a lot of EPO budget these days, in addition to 42 minutes being an eternity. It's a great documentary, and, I think, a treasure.
