Each movie will be a cut-down version of the corresponding Episode from the OT. I'll be using footage mainly from the SE, as well as from Darth Editous's edit of ANH as the basis for that episode. Flashback footage will come from the PT DVDs. I very briefly considered using some Clone Wars footage, while discussing this project with my roommate, but decided to keep everything purely live-action. Too many inconsistencies in introducing cartoon footage into what will otherwise be a serious project.
Thanks for the suggestion about title cards though!
