After reading about it over and over in my film classes, I finally watched Battleship Potemkin tonight. It was pretty interesting but nothing too amazing (nowadays, at least). It was notable back then for its use of editing to maximize the viewer's emotions, and for the particular use of montage. Apparently, the scene where the soldiers march down the stairs influenced the raid on the Jedi Temple in ROTS, though I'm not sure how true that is.
