Star Wars: Episode II – Attack of the Clones2000

[Count Dooku tries to recruit Obi-Wan into the Separatist cause]

Count Dooku:
It's a great pity that our paths have never crossed before, Obi-Wan. Qui-Gon always spoke very highly of you. I wish he were still alive. I could use his help right now.

Obi-Wan:
Qui-Gon Jinn would never join you.

Dooku:
Don't be so sure, my young Jedi. You forget that he was once my apprentice, just as you were once his. He knew all about the corruptions of the Senate, but he would never have gone along with it if he had learned the truth as I have.

Obi-Wan:
The truth?

Dooku:
The truth. What if I told you that the Republic is now under the control of the Dark Lords of the Sith?

Obi-Wan:
No, that's not possible! The Jedi would be aware it!

Dooku:
The dark side of the Force has clouded their vision, my friend. Hundreds of senators are now under the influence of a Sith Lord called Darth Sidious.

Obi-Wan:
I don't believe you.

Dooku:
The Viceroy of the Trade Federation was once in league with this Darth Sidious, but he was betrayed ten years ago by the Dark Lord. He came to me for help; he told me everything. The Jedi Council wouldn't believe him. I've tried many times to warn them, but they wouldn't listen. By the time they sense the Dark Lord's presence, it would already be too late. You must join me, Obi-Wan, and together we will destroy the Sith!

Obi-Wan:
I will never join you, Dooku.

Dooku:
[coldly] It may be difficult to secure your release.
