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.
Braveheart gets so close - as long as you don't think too hard about how all of the named characters are nobles and all of the people dying by the hundreds are peasants.
