The Empire Strikes Back1980

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

[Vader severs Luke's hand with his lightsaber. Luke screams in pain.]

Vader:
There is no escape. Don't make me destroy you. Luke, you do not yet realize your importance. You've 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:
[wincing] I'll never join you!

Vader:
If only you knew the power of the dark side. Obi-Wan never told you what happened to your father.

Luke:
He told me enough. He told me you killed him.

Vader:
No. I am your father.

Luke:
[shocked and horrified] No. No. That's not true! That's impossible!

Vader:
Search your feelings. You know it to be true.

Luke:
NOOOOOOO!!!! NOOOOOOOO!!!!

Vader:
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. [Luke looks down the shaft and then back at Vader] Come with me. It is the only way. [Luke lets go of the projection and falls into the shaft]
