Star Wars: Episode V - The Empire Strikes Back

Lando Calrissian: "Princess, we'll find Han. I promise."
Luke Skywalker: "Chewie, I'll be waiting for your signal. Take care, you two. May the force be with you."

[Chewbacca is carrying the dismembered C-3PO on his back]
C-3PO: "If only you'd attached my legs, I wouldn't be in this ridiculous position. Now remember, Chewbacca, you have a responsibility to me, so don't do anything foolish!"

Princess Leia: "I love you."
Han Solo: "I know."

Han Solo: "You said you wanted to be around when I made a mistake, well, this could be it, sweetheart."
Princess Leia: "I take it back."

"Luke, you can destroy the Emperor. He has foreseen this. It is your destiny. Join me, and together we can rule the galaxy as father and son."

Darth Vader: "There is no escape. Don't make me destroy you. Luke, you do not yet realize your importance. You have only begun to discover your power. Join me, and I will complete your training. With our combined strength, we can end this destructive conflict and bring order to the galaxy."
Luke Skywalker: "I'll never join you!"
Darth Vader: "If you only knew the power of the Dark Side. Obi-Wan never told you what happened to your father."
Luke Skywalker: "He told me enough! He told me you killed him!"
Darth Vader: "No. I am your father."
Luke Skywalker: "No... no. That's not true. That's impossible!"
Darth Vader: "Search your feelings, you know it to be true!"
Luke Skywalker: [cries in anguish] "No! No!"

"You are beaten. It is useless to resist. Don't let yourself be destroyed as Obi-Wan did."

Darth Vader: "Your destiny lies with me Skywalker. Obi-Wan knew this to be true."
Luke Skywalker: "No...!"
