No, not that one.
Not that one, either.
And not this one.
The guy who wore the suit and helmet majestically in the first three Star Wars movies (based on release date not story chronology) has prostate cancer.
Star Wars fans know that we did see him, briefly. While lying close to death near the end of Return of the Jedi, Vader has Luke Sywalker remove the helmet so that he can look upon his son with his "own eyes." In the version of Jedi that they play on TV these days, they also seem to have Luke looking at a hologram of a Christiansen-Annakin with Yoda and Obi-Wan Kenobi after Vader's funeral. It used to be Prowse in that hologram.
