From StarWars.com: Episode III will further connect the Star Wars saga, bridging the prequel trilogy to the original trilogy in new and surprising ways. As such, familiar faces and places will return in this new Star Wars film, which is currently in pre-production. Reprising their classic roles from the original trilogy are actors Peter Mayhew, Anthony Daniels and Kenny Baker. They return to Star Wars as Chewbacca the Wookiee, C-3PO and R2-D2. "I'm delighted to return as Chewbacca," says Mayhew. "I think his re-appearance in this film is a fitting way to tie the whole saga together, especially for Wookiee fans." Given that Chewbacca is a sprightly 200 years old in Episode IV, he is more than old enough to fit into the prequel timeline. Now I'm really excited about Episode III!
