Ok folks, here I am...
Ok, Darthran, let's go through this step by step. Though it's a little difficult to follow you sometimes, as you at first say C. Lee is too old to have the skill, and then later say that it is not the skill you are worried about, just the age. You also say that Dooku is too old and then say the name of Sidious as intimidating. Odd. But never mind.
First of all you need to totally lose the mindset that you need to be a young, spritely martial artist to make a sabre fight look good. You express a certain horror that the fight will be like the one between Obi-Wan and Vader in ANH. Personally, I see no real problem with that at all; that was the most technically accurate fight (well, as accurate as you can be with sci-fi weapons), it was laden with emotion, and was a perfect example of two ageing Masters facing off in a battle of wills and skill. That said, fights like that are never going to look as exciting as the others, so once is probably enough.
You in any case need never fear, for there are three reasons why the Dooku duel will NOT be like that.
1. They have already done it. Each fight has been rather different from the one before, so far.
2. It would make no sense. The ANH duel was between TWO people with diminsihed physical capacities. This fight only involves one. At its very basic level it has to be an entirely different experience.
3. Rather more tellingly, the brief shot of the fight in the trailer shows it to be very much not like the ANH one! Rather like that shot we have of Dooku expertly wielding two sabres at once.
So don't worry about that.
But to get back to my basic point; have you ever seen old Kendo masters fight duels? It is the most amazing thing. They are not playing to kill, of course, but the principles are identical. These wrinkly old guys go up against people four times less old than them. The youngsters have massive advantages in speed and strength and agility; they can perform moves that would snap the old guy's spine if he tried it.
But the old guys keep winning. And, my, does it look marvellous! It's just the way they MOVE! It almost totally humiliates the younger ones, if it weren't for the fact that the younger ones seem pretty honoured to be up against such an opponent! Learning a few things for later life, I am sure.
Any swordfighter who relies on strength, speed and agility will be dead by the time he is thirty- or at least out the business. SKILL is the only thing that keeps you in that game. You will be amazed how more important it is than youth- and amazed how good it will still look.
Obviously, C. Lee won't be doing any flips himself, unless they bring a double in. But the OTHERS will, and that will look just fine! After all, Maul did nearly all the flips against more conventional opponents in TPM. And as far as I am concerned, the sight of an old Swordmaster calmly and competently fending off the frenzied acrobatic attacks of his younger opponents- especially Anakin- makes me almost giddy. If it's done right it will look far better than TPM!
And I have every confidence that it WILL be done right. My fellow members have already provided the evidence here. C. Lee is in amazing shape for his age, He is a VERY good swordsman. Ewan McGregor is also a good swordsman. I saw an interview with Nick Gillard last week in which he said Hayden Christensen was the fastest learner he had ever seen- his praise seemed enormous and genuine.
And finally we come down to Nick Gillard himself, a man I have enormous confidence in. A man who has already proved to everyone that he has what it takes to deliver the most stunning sabre fights (now, if that could only be paired with the emotional resonance of the Original Trilogy fights... oh man. Roll on Episode III!).
And let's not forget any possible surprises and tricks that Nick has waiting for us. Maybe Dooku has better physical capciities than are at first apparent. Or maybe not. Whatever, so long as it is done well.
So... anyway... with all that in mind.,.. quite frankly, you will have to give me overwhelming evidence that the coming fight will be rubbish before I believe it! Personally, I think casting an OLD Sith to replace Maul is possibly the best move of the prequel trilogy so far.
