Star Wars: Episode III – Revenge of the Sith2005

[Anakin stops Mace Windu from hurting the Chancellor, severing Windu's hand. Sidious drops his act and again strikes Windu with force-lightning]

Sidious:
[Triumphantly] POWER!!!! UNLIMITED POWER!!!! [sends Windu flying out the window to his death]

Anakin:
[Horrified] What have I done...?!

Sidious:
You're fulfilling your destiny, Anakin. Become my apprentice. Learn to use the dark side of the Force.

Anakin:
[exhausted] ...I will do whatever you ask.

Sidious:
Good!

Anakin:
Just help me save Padmé's life. I can't live without her.

Sidious:
To cheat death is the power only one has achieved, but if we work together, I know we can discover the secret.

Anakin:
I pledge myself... to your teachings.

Sidious:
Good. Good... The Force is strong with you. A powerful Sith, you will become. Henceforth, you shall be known as Darth...Vader.

Darth Vader:
Thank you, my master.

Sidious:
Rise...[Vader rises and Sidious goes to his desk] Because the Council did not trust you, my young apprentice, I believe you are the only Jedi with no knowledge of this plot. When the Jedi learn what has transpired here, they will kill us, along with all the Senators.

Vader:
I agree. The Council's next move will be against the Senate.

Sidious:
[Places hood on his head] Every single Jedi, including your friend, Obi-Wan Kenobi, is now an enemy of the Republic.

Vader:
I understand, Master.

Sidious:
We must move quickly. The Jedi are relentless. If they are not all destroyed, it will be civil war without end. First, I want you to go to the Jedi Temple. We will catch them off balance. Do what must be done, Lord Vader. Do not hesitate. Show no mercy. Only then will you be strong enough with the dark side to save Padmé.

Vader:
What about the other Jedi spread across the galaxy?

Sidious:
Their betrayal will be dealt with. After you have killed all the Jedi in the Temple, go to the Mustafar system. Wipe out Viceroy Gunray and the other Separatist leaders. Once more the Sith will rule the galaxy! And... we shall have... peace.
