The Working Class Goes to Heaven (1971)
A messy but interesting film. Bonus: it featured lots of machining, though much of that was more of a cautionary tale when it comes to shop safety.
This one proved elusive, as it's not available for streaming, but luckily Scarecrow, the one big (really big!) rental store left in town, had a copy. Except the first time I carelessly grabbed the Blu-Ray instead of the DVD, and my region-free player is DVD only. Whoops. I'm enjoying going to the rental store after brunch as part of my normal Saturday routine, though. I think I'll keep doing that, even when everything on the docket is available streaming. Gods know that Google and Amazon don't need any more of my money.
