Some things I've been looking at are using the variations in voices on the Spanish/French audio track for Vaders "No" and some of the Emperor's babble.
Here are some scenes I though made more sense to Anakins transformation:
"Sidious Revealed"
Anakin: Chancellor....we just recieved a report from master Kenobi, he has engaged General Grievous.
Palpatine: We can only hope master Kenobi is up to the challenge.
Anakin: I should be there with him.
Palpatine: It's upsetting to me that the council doesn't seem to fully appreciate your talents, don't you wonder why they won't make you a Jedi master?.
Anakin: I wish I knew, more and more I get the feeling that i'm being excluded from the council....I know there are things about the force that they're not telling me.
Palpatine: They don't trust you Anakin, they see your future, they know your power will be too strong to control.
*Edit* when their backs turn to walk into the other room i've replaced the "you must break through the fog of lies"dialogue with: "Ever since I've known you you've been searching for a life greater than that of an ordinary Jedi.
Palpatine: Let me help you to know the subtleties of the force.
Anakin: How do you know the ways of the force?
Palpatine: My mentor taught me everything about the force, even the nature of the dark side.
Anakin: You know the dark side?
Palpatine: Anakin, if one is to understand the great mystery, one must studey all it's aspects.
*Cut out* "Not just the dogmatic narrow view of the Jedi"
Palpatine: If you wish to become a complete and wise leader, you must embrace a larger view of the force...be careful of the Jedi Anakin, only through me can you achive a power greater than any Jedi...learn to know the dark side of the force and you will be able to save your wife from certain death.
Anakin: What did you say?
Palpatine: use my knowledge, I beg you.
*Cut out* Everything up to......
Anakin: I'm going to turn you over to the Jedi council.
Palpatine: Of course you should but you're not sure of their intentions are you?
Anakin: I will quickly discover the truth to all of this.
Palpatine: You have great wisdom Anakin....know the power of the dark side, power to save Padme'
I actually hated to cut out Anakin threatening Palpatine with his lightsaber, and Palpatine's I feel your anger segment...But I felt that it undermined showing that Anakin was being swayed by Palpatine if he is shown wanting to kill him.
"Anakin/Windu in the hanger"
Anakin: Master Windu, I must talk to you.
Windu: Skywalker we have just recieved word that Obi- Wan has destroyed General Greivous...we're on our way to make sure the chancellor returns emergency power back to the senate.
Anakin: He won't give up his power, I just learned a (removed terrible) truth.....I think Chancellor Palpatine is a sith lord.
Windu: A sith Lord?....how do you know this?
Anakin: He knows the ways of the force....he's been trained to use the dark side.
Windu: Are you sure?
Anakin: Absolutely.
Windu: (removed: then our worst fears have been realised) We must move quickly if the Jedi order is to survive.
(removed: Master the chancellor is very powerful, you will need my help if you're going to arrest him.)
Windu: For your own good stay out of this affair...I sense a great deal of confusion in you (removed young skywalker)
Anakin: I must go master.
Windu: If what you have told me is true you will have gained my trust, but for now remain here, wait in the council chambers until we return.
Anakin: (removed yes master).
This makes Windu colder toward Anakin again brushing him aside....Anakin sounds more matter of fact about Palpatine being a sith.
And the following scenes with Windu/Palpatine/Anakin is a vast improvement, but i't's better seen than heard....and i'm sure most couldn't care less about reading all this, I thought i'd give a few examples of a few changes I made.
