Arabella Bishop: I believe you're talking treason.
Dr. Peter Blood: I hope I'm not obscure.

Maj. Clipton: The fact is, what we're doing could be construed as - forgive me sir - collaboration with the enemy. Perhaps even as treasonable activity. Must we work so well? Must we build them a better bridge than they could have built for themselves?

Lady Marian Fitzswalter: Why, you speak treason!
Robin Hood: Fluently.

Captain von Trapp: [after pulling the gun from Rolfe] You'll never be one of them.
Rolfe: Lieutenant! Lieutenant, they're here! They're here, Lieutenant!
[blows whistle]

Herr Zeller: Perhaps those who would warn you that the Anschluss is coming - and it is coming, Captain - perhaps they would get further with you by setting their words to music.
Captain von Trapp: If the Nazis take over Austria, I have no doubt, Herr Zeller, that you will be the entire trumpet section.
Herr Zeller: You flatter me, Captain.
Captain von Trapp: Oh, how clumsy of me - I meant to accuse you.

[after King Henry VIII leaves]
Alice More: What's this? You crossed him?
Sir Thomas More: Somewhat.
Alice More: Why?
Sir Thomas More: I couldn't find the other way.
Alice More: You're too nice altogether, Thomas.
Sir Thomas More: Woman, mind your house!
Alice More: I am minding my house!

Michael 'Beau' Geste: There'll be a flag flying out there in the morning that I swore to uphold. Armies of good men have died for it gladly. It's a battle flag and it's a flag of victory. I'm rather proud to be under it. And I wouldn't want to go out in the morning like you and know that I was going to be a traitor to it!

Senator Joseph Paine: Let me go! I'm not fit to be a senator! I'm not fit to live! Expel me, not him! Willet Dam is a fraud! It's a crime against the people who sent me here - and I committed it! Every word that boy said is the truth! Every word about Taylor and me and graft and the rotten political corruption of my state! Every word of it is true! I'm not fit for office! I'm not fit for any place of honor or trust! Expel me, not that boy!
