Even those of you who are not huge fans of the Star Wars movies will be aware of the Darth Vader character and will also be aware of his trademark voice.
the voice of Darth Vader is not actually the voice of the man (David Prowse) who is inside the Darth Vader costume. Take a look at this rare video of Star Wars as it was been made and before the voice of Darth Vader was overdubbed with that of James Earl Jones.
David Prowse, the actor in the Darth Vader costume has actually said many times that he is surprised that George Lucas did not use his voice for the role. What do you think?
