In related news, actor David Prowse, who played Darth Vader in Star Wars: Episode IV - A New Hope, Star Wars: Episode V - The Empire Strikes Back and Star Wars: Episode VI - Return of the Jedi, revealed in a recent interview he wants to return to play a new character in Star Wars: Episode VII.
"Unfortunately, Darth Vader was killed off. But it would be nice to come back and do another character, because no one's ever seen my face. I was never unmasked."
