Looks like a really interesting list of changes Spence :) I look forward to seeing where you take the movie! Couple of added suggestions... Anyway you could make Anakin a bit older?Like having a charachter say he's 11 or 12? Other request is remove any references too Padme being elected... Who elects 14 year olds?

With regards the Energy Source, could the Duel of Fates fight be in the reactor system? Always seemed entirely random where that fight was, considering they were in the middle of a palace and suddenly those huge power colums etc...

I also reckon if there is no reveal as to who Sidious is, it maybe worth leaving in the discussion between Yoda and Mace about there being Master and Apprentice (though I know some hate it).

For Mauls voice would something similar to Darth Sion's voice in KotOR 2 work well http://www.youtube.com/watch?v=DVQJwIrswMs ??
