Watching El Golpe Blanco (1975) right now about the attempt for a parliamentary coup by reaction in Chile before the military coup. Flick opens with a shot of Langley and a voiceover from UK journalist and defector to the GDR John Peet where he just shrugs off "CIA headquarters in Langley near Washington: one of the instruments of US monopoly capital in its global strategy of counterrevolution." Like there's no bullshit, no both sidesing, just plainly calling a spade a spade so refreshing.
It's hard to find but you can get links to it here https://www.umass.edu/defa/film/9642. Also, the free streaming service Kanopy has a ton of DEFA flicks to work your way through, all you need is a library card.
I've not watched it yet, as I don't have the spare cash right now, but in another post some months ago someone recommended The Subversive Camera.
