How do you get banned from appearing at official Star Wars conventions?
If you follow the dark path blazed by actor David Prowse,who was the man in the Darth Vader costume in the original trilogy, you do so by going public with claims that you have never been paid residuals for Return of the Jedi because it has never turned a profit.
Never fear, convention-goers: You may not be able to see Prowse at Lucasfilm-sanctioned events like Star Wars Celebration V, but he wants you to know that he will continue to make appearances at other events not affiliated with the Empire.
