Thinking about how one of my favorite moments in Star Wars is one that doesn't actually have any dialogue.
In The Phantom Menace when Qui-Gon and Darth Maul are fighting each other and then get cut off by the laser wall between them there's a great bit as the two are waiting for it to open back up. Qui-Gon just sits down to compose himself while Maul is pacing like a caged tiger and takes a swipe at the laser wall with his lightsaber, which doesn't do anything.
