James Franco for sure as Anakin.

Ewan McGregor would stay as Obi Wan, he was just that good to me.

I just did not like Natalie Portman, but I can't think of who to replace her with so....

I just LOVED Samuel Jackson as a Jedi, however, I do not think he should have been Mace Windu. Mace Windu should have been a reserved, typical, Jedi Master. *MAY BE BREAKING RULES HERE* I think there should have a whole new Jedi role written for Samuel. I always imagined a hardcore, really close to the dark side, Jedi Knight who does not trust Anakin from the word go and tries in vain to warn everyone that it is a huge mistake to take him on. Everyone just brushes him off and writing away his warnings as just being rebellious and overwhelmed in jealously. However, in the end he is found to be right and is the last chance the Jedi Counsel has against Darth Vader, but he loses to the far more powerful Darth Vader. I thought that would have been a great arc that could been played well through all three prequels. *SORRY FOR BREAKING RULES* Anyhow, Mace Windu, should have been Lawrence Fishburne. More reserved, less intense than Samuel. But I reckon he was busy that year with the Matrix and all.

Jimmy Smits was perfect for Bail Organa.

I agree with C3PX, Michael Biehn would have been SUPERB as Jango, Boba, and the Clones. Also, more "Aryan", which is what I believe Palpatine was going for.

I would have Jar Jar replaced with nitrogen, oxygen, water vapor, argon, and carbon dioxide.

Liam Neeson was great.
