SLJ was on fox sports & this is what he had to say AUG 13 2003 :

He said that it takes a lot of athleticism to play a Jedi Knight. He also mentioned that it took three days for him to learn a 88 move lightsaber duel. He also mentioned he was the one being attacked  in the duel but never mentioned who was the attacker & that he jumps over steps & various  other things  SLJ also said he thought it was  difficult  to learn being in a scene that involved him being  backed up & on the defense the whole fight.

Cinescape reported in 1999

Rick macallum told dutch publications SUM in 1997 that we will see Anakin rise through the jedi ranks from pedawan learner we see at the end of episode 1 to jedi knight to the lofty station of jedi master  based on his heroism in the clone wars but at the height of his pride gets caught up in his own ego & makes a self serving choice to turn to the dark side
Jake loyd episode TPM teased the Australia’s Herals newspaper he said Anakin only went to the dark side because he was forced to .did you know that ? Anakin did not have enough will power not to that was his weekness loyd explained (sort of like when luke faced the empror but he had the will power not to give in to the dark side )

Lucas on Boba fett :
Starlog Magazine:
GL: Boba will be in Episode III, but his role definitely won't be larger. He's in a transition period of becoming a bounty hunter. The next film takes place two or three years later, so Boba would only be 13 and still wouldn't fit the suit

August 08, 2003; Hyperspace: "The Halfway Point":
• Today's shooting continued with somber scenes.

• The new Jedi starfighter is designed with a removable cockpit.

• Anakin, Obi-Wan Kenobi and Plo Koon and other Jedi will fly starfighters. Today's shooting filmed a Jedi being destroyed by enemy fire from behind.

• Shooting is now half-way complete with only 30 days to go.

August 07, 2003; Hyperspace Webchat with Anthony Daniels - A Summary:
• Due to the shiny hue of C-3PO's suit, the droid will undergo different suit variations due to the shooting against blue & green screen backgrounds. Perfection of the suit coloring on-screen will be done in post-production.
• The most difficult scenes to perform are those that involve steep inclines, such as a ship ramp. (Hasbro toy reference, see previous HS article about 3PO on a ramp)
• Anthony made a script change suggestion to George in order to change the word "hurt" to "damage" and it was approved.

• McCallum read the completed script only 10 days before production started and agrees with Lucas's summary. "It is a darker film and it's much more complex emotionally," he says. "Everybody knows Anakin Skywalker has to turn into Darth Vader, we just don't know the how and the why of it. That's what drives the drama of this one."

• As for keeping the ending a secret . . . well, the finale to Episode III was revealed in 1977 in the original film, Star Wars: A New Hope (Episode IV in the saga): Skywalker betrays the Jedi Order and hunts down and murders the remaining Jedi Knights; Padme Amidala, Skywalker's wife, gives birth to twins, Luke and Leia, but they are hidden from their father for their protection; Skywalker suffers serious injuries after a battle with Obi-Wan Kenobi and he becomes more machine than man in his recovery, to complete his transformation into the evil Darth Vader.

• "We are hoping it will be the shortest of all of them but it will probably end up at about exactly the same time – two hours and 10 minutes," he says.

• "This is about not really moving from II to III, this is about linking III to IV and tying up all the loose ends. So somebody who doesn't understand Star Wars can start with Episode I and follow the whole saga, the whole family all the way through. Personally, I think this is the coolest of the lot but I also thought that about Episode I and II."
