Well the end idea is semi like you stated, His eyes will turn as he starts his attacks after Dooku taunts him. During the shot that i posted, his eyes will be sith thruout, This was sort if a test on doing the slow fade from normal to sith eyes. The eyes will remain untill after Anakin kills Dooku.

I understand your point about when Anakin has the eyes in the Original tho. But alot of things are changing from the Original, for the sake of better storytelling.

Also, this was kind of just something I decided to try, editing wise. So it actually might not even make it into the edit. Havnt decided on it yet. But at least I know it's possible for me to do it. When I really want to add a slow fade to Sith eyes is when Obi is telling Anakin that he's not on his side. During the closeup of Anakins face, right before he does the backflip to start there duel.
