Oh, one more thing pertaining to ALL the prequels, "Annie" must be eliminated wherever possible. I'd say Shmi should be the only one to call him that.

So here's some dialogue for a Sith explanation scene in the place of the Midichlorine scene:

ANAKIN: Qui-Gon, sir, I don't want to be a problem.
QUI-GON : You won't be Anakin. I'm not allowed to train you, so I want you to watch me and be mindful. Always remember, your focus determines your reality.
ANAKIN: Master sir, I've been wondering, what are Sith?
QUI-GON: Agents of evil, adversaries of the Jedi and followers of the Dark Side of the Force. A thousand years ago the Jedi and Sith fought a great war in which the Sith were exterminated, or thought to be.
ANAKIN: What could they want now?
QUI-GON: Vengence. There is something else behind all this but for now their motivations remain a mystery.
ANAKIN: So what are the Jedi going to do?
QUI-GON: Whatever is necessary. Don't worry, Anakin. Stay close to me and you'll be safe.

So that's a basic outline of what I was thinking for the scene. If anyone has any ideas on where to get clips that might work for something like this (other movies, interviews, etc.) please don't keep them to yourself.
