Star Wars: Episode V - The Empire Strikes Back

"Impressive. Most impressive. Obi-Wan has taught you well. You have controlled your fear. Now, release your anger. Only your hatred can destroy me."
[to Luke]

Darth Vader: "You have learned much, young one."
Luke Skywalker: "You'll find I'm full of surprises."

"The force is with you, young Skywalker, but you are not a Jedi yet."

Lando Calrissian: "Lord Vader, we only use this facility for carbon freezing. If you put him in there it might kill him."
Darth Vader: "I do not want the Emperor's prize damaged. We will test it on Captain Solo."

"Someday you're gonna be wrong, I just hope I'm there to see it."
[to Han Solo]

"You have your moments. Not many of them, but you do have them."
[after Han Solo reveals his clever plan of escape]

[Interrupting Han and Leia kissing]
C-3PO: "Sir. Sir, I've isolated the reverse power flux coupling."
Han Solo: "Thank you. Thank you very much."
C-3PO: "Oh you're perfectly welcome, sir."

Han Solo: "Hey, Your Worship, I'm only trying to help."
Princess Leia: "Would you please stop calling me that?"
Han Solo: "Sure, Leia."
Princess Leia: "You make it so difficult sometimes."
Han Solo: "I do, I really do. You could be a little nicer, though. Come on, admit it. Sometimes you think I'm all right."
Princess Leia: "Occasionally, maybe... when you aren't acting like a scoundrel."
Han Solo: "Scoundrel? Scoundrel? I like the sound of that."
[Han starts to massage Leia's hand]
Princess Leia: "Stop that."
Han Solo: "Stop what?"
Princess Leia: "Stop that. My hands are dirty."
Han Solo: "My hands are dirty, too. What are you afraid of?"
Princess Leia: "Afraid?"
Han Solo: "You're trembling."
Princess Leia: "I'm not trembling."
[Han gets closer]
Han Solo: "You like me because I'm a scoundrel. There aren't enough scoundrels in your life."
Princess Leia: "I happen to like nice men."
Han Solo: "I'm a nice man."
Princess Leia: "No, you're not. You're..."
[Han kisses Leia]
