Serious answer: TIE fighter pilots climbing into their ships against the backdrop of The Eye, with the klaxons fitting perfectly with the music.
There are so many good ones but here are a couple that came to mind when I saw this question:
From RotJ: “Never. I’ll never turn to the dark side. You’ve failed, your highness. I am a Jedi, like my father before me.”

From Andor: Kino Loy’s “one way out” monologue over the intercom during the prison break.
