Want to know a description of the animatics of Episode II they were running during filming? Lucas likes to watch what he has filmed on huge 40" monitors and at the same time run rough animatics of the scene. Here's a spoiler report from some of the action seen:

Yoda intercepts after Dooku has stabbed ObiWan in the shoulder with his 'walking stick like' lightsabre (red blade, kind of bent handle - fights like he's fencing, Ep IV style), Anakin then has a go at him and uses the force to pick up Obi-Wan's blade - then fights the Sith with two lightsabers. But Dooku beats Anakin and finally Yoda has to step in.

We saw a bit of Dooku speeding across the wastelands to his cavern-like lair (this was all in marker renderings, obviously no graphics done at that stage.)

A bit in Dooku's 'Box' in the arena on Geonosis, Also present was Jango Fett and Mace Windu holding is 'off' lightsaber directly onto his throat! Oh man, you're going to love Jackson in this one.

Darth Yen has promised more shortly as well, including new details from the shoot as well.
