For my prequel re-write I've been thinking about casting and stuff.
Due to the fact that nearly all the bad guys in the OT have English accents and the good guys have American accents, How about all the 'good guys' in the prequels have British accents and the 'bad guys' have American ones, because technically the 'good guys' aren't the bad guys yet... if that makes sense.
The higher up people would have 'BBC' accents, whilst the lower down people would have Welsh, Irish, Scottish 'cockney' and american accents. Maybe a couple of Canadians as well.
Also I've been thinking that filming for scenes that are set on the Clone's homeworld should be done in a quarry (a la Dr Who) It would give it a barren landscape... thingy.
Also, What do think of 'The Oncoming Storm' for the title for Episode One?
