*Dooku sounds like something a 6-year-old would come up with while playing in the front yard.

I've heard that Lucas personally pronounces it Doh-ku, which actually makes it sound cool. I don't know why everyone else decided to run with the infantile pronunciation.

I've also noticed that Lucas pronounces "Gungans" as "Gungas" and calls "Light Sabers", "Laser Swords". Mind you Patrick Stewart spent a whole interview on the radio the other day talking about his X-Men character "Zaviour" that he's only played for oh 14 years. Senility happens to the best of us ;-)

That's actually how the name is pronounced in most real-world instances. Stewart must have just forgotten that his character mispronounces his own name. ;)

Otherwise, how would we remember that he leads the X-Men?

On topic: the scripts for the original 1977 SW film used "laser swords" instead of "lightsabers" until the third draft or so, which is probably why it sticks in Lucas's head. Even in the later drafts, "lightsaber" is used purely in dialogue, and the script directions still say "laser sword."
