If they have Mace Windu in the new trilogy, naturally it's assuming he survived that Force Lightning raping he recieved in Revenge of The Sith, he's going to be older than fuck. Alec Guinness couldn't sabre to save his life (probably why he let Vader kill him) but if they put enough prostetics on Jackson he might be able to pull it off.
Perhaps a movie showing the crazy years of C3PO and R2D2 with Captain Antillies, the wacky adventures those two must've gone through...
