Movies where the thematic elements revolve around a group of people banding together against an oppressive force, but not really a chosen one style story. I have Braveheart in mind but I don’t know if that really hits the same notes, because so much of it is also a love revenge story.
The Bader-Meinhof Complex (2008) is about the Red Army Faction
Shock Troops (1967) is about the Maquis in Vichy France
State of Siege (1972) is about the Tupamaros in Uruguay abducting Dan Mitrione.
Out of these three, State of Siege is the by far the coolest.
