Superman 2 (1980)

General Zod: [looking at the Presidential Seal on the floor of the Oval Office] I see you are practiced in worshiping things that fly. Good. Now, rise before Zod.
[the "President" stands up]
General Zod: Kneel before Zod.
[the "President" kneels]
General Zod: You are not the President. No one who leads so many could possibly kneel so quickly.
President: [appears from behind the other men] I'm the man they're protecting. I'm the President. I'll kneel before you, if it will save lives.
General Zod: It will, starting with your own.
Ursa: [walking towards a group of military men] What a backwards planet this must be, where the men wear the ribbons... and the jewelry!
[rips the ribbons off a general's uniform]
President: What I do now, I do for the sake of the people of Earth. But there is one man on this planet who will NEVER kneel before you.
General Zod: Who is this imbecile? Where is he?
President: I wish I knew.
[kneels]
