If you're interested in history, it's worth seeing this documentary on World War I (specifically, what it was like in the trenches for the British Army, though Peter Jackson commented that he expects the trench experience would have been the same for any WWI army).
Fair warning, the restored footage includes footage of battle injuries and corpses. The bit that really grossed me out was the guy with trench foot who hopefully was getting those toes amputated after that bit of film was shot.
There's one more US showing after Christmas through Fathom Events: https://www.fathomevents.com/events/the ... t-grow-old . Last night's showing included about half an hour after the credits on how and why Jackson made the film, hopefully the repeat showing will include that as well.
