Like the casting breakdown for the upcoming Star Wars: Episode VII, “Rebels'” primary characters will all be teenagers. The reason behind this is to give the show a skew toward younger audience members. In addition, the site says that Mark Hamill will provide a guest voice for the show in some capacity.
Star Wars Rebels takes place in a time where the Empire is securing its grip on the galaxy and hunting down the last of the Jedi Knights as a fledgling rebellion against the Empire is taking shape.
Star Wars Rebels will be produced by Lucasfilm Animation, featuring many of the key talents that made Star Wars: The Clone Wars. Fans attending Star Wars Celebration Europe will be the first to get an exclusive look at the new series. Casting will be announced at a later date.
