When the Jedi bump into Count Dooku while trying to rescue the kidnapped Chancellor, it's the ultimate grudge match. What the Jedi don't know is that the one they're trying to save is the one who has perfectly orchestrated everything. Dooku is far too trusting of his master and that was his downfall. Of course, Anakin Skywalker has something to do with that as well.
The duel with Dooku is pretty much as scripted outside of a few minor lines that we didn't see in the final version. Here are some bits of dialogue from the published script that didn't survive. Some are just more of Palpatine or Dooku goading, some are just extra words from Anakin. I especially like Dooku calling Obi-Wan's moves "clumsy." These passages are from the published screenplay:
Good. Twice the pride,
double the fall.
DOOKU lunges at the JEDI and they fall back...
COUNT DOOKU (continuing)
Your moves are clumsy, Kenobi...
too predictable. You'll have to do better.
Good, Anakin, good.
I knew you could do it.
Kill him. Kill him now!
ANAKIN cuts off COUNT DOOKU's head. A huge EXPLOSION somewhere deep in the ship rattles everything.
I couldn't stop myself.
You did well, Anakin.
He was too dangerous to be kept alive.
ANAKIN drops COUNT DOOKU's lightsaber, moving to PALPATINE.
Yes, but he was an unarmed prisoner.
ANAKIN raises his hands toward PALPATINE, who is strapped in the Admiral's Chair. The Chancellor's restraints pop loose.
I shouldn't have done that, Chancellor.
It's not the Jedi way.
PALPATINE stands up, rubbing his wrists.
He seems to be all right.
No broken bones,
breathing's all right.
Leave him, or we'll
never make it.
I quite enjoy the fact that Palpatine tried to rid himself of Obi-Wan Kenobi and Anakin never even picked up on it. He never even really questions him about why he'd leave his "partner" behind.
There's another line of dialogue not included in the screenplay excerpts above that I need to mention, mostly because there's footage of it! Right before the Jedi start to duel Dooku, he says to them, "Just because there are two of you, don't assume you have the advantage." While I can only speculate as to why this was deleted, my gut tells me that it's somewhat redundant dialogue. Dooku already says, "Twice the pride, double the fall," even though in the film he says it a short time afterwards and the context is different as he's referring to Anakin saying his powers have doubled. That's all I can think of, other than the theory that Lucas just didn't like the line there.
Either way, it was removed from the film, but you can catch this extra bit of footage fully intact in the EPISODE III video game. Thanks to those who wrote in with the alert and special thanks to Trevor Davey and Mark Serratore for their great help in providing the video clip which you can download below.
Moving on, check out the images from the Comic Adaptation below and take note of all the subtle differences between the script, the comic, and the finished film. For example, in the comic, Anakin only takes one of Dooku's hands. It's especially interesting to note that the comic pretty much skips all the elevator antics and goes straight to the ray shields scene, with Obi-Wan waking up right after Dooku dies saying it's a pity that he's dead. Did an early version of the script contain this dialogue? Did an earlier version have Obi-Wan waking up so soon? Who wrote this dialogue if it was never supposed to be in the film? When I have more definitive answers, I'll let you know. However I did talk to a friend at Dark Horse comics who told me that at one point Obi-Wan's lines were in the script, since the comic was based entirely on an old version.
One photo below that isn't from the comic definitely generated some enthusiasm for me personally when I first saw it. If you look below, you'll see Palpatine in his chair with lightsabers crossed in front of him. This isn't in the film but it mirrors a similar shot from RETURN OF THE JEDI where Vader and Luke clash sabers before a cackling Palpatine. This image was out long before the film was so I was a little surprised when it wasn't in the final edit. I thought it was a nice little connection to the original films. So be it...Lucas.
