I think the last memorable one was director Carol Reed's "The Third Man" Starring Joseph Cotton and Orsen Wells.
Likely a top 25 Best film ever seen on my list maybe even top 10.
I happened by an HBO series Our Boys about Families and their teen kids and conflicts on the Gaza strip a few years ago. It was subtitled but I couldn't stop watching it. It was not a documentary but based on real events, I recommend it.
