David Prowse played the part of Darth Vader in the Star Wars movies and should receive residual checks for his role. There are many contract stipulations that are established for actors that may include a profit criteria. The standards for movie studios need to be reviewed for fairness and transparency so that all actors are treated appropriately.
What happened in Hollywood is not a surprise. It is understandable that in such big dollar- industry, mafia network is real. If we can bring standards to this industry, i think, it would be a good news. Indeed, every people working on a film would be paid more equally or on a clear base.
Accounting standards should be made tougher for Hollywood movie studios. Popular and enormously successful movies such as Return of the Jedi have not turned a profit, and David Prowse hasn't received a royalty check. Accounting is supposed to reflect reality, and by any measure, including ticket and video sales, the movie should be profitable, except for accounting gimmicks.
While it's common practice that Hollywood movie producers create a new company entity for each movie produced the dirty secret of the accounting practices is finally getting some air time. Going back several years of news events, many movies are seeming blockbusters at the theatre to keep the hype alive and well bringing in revenues based on views. In reality those revenues don't always go back to the persons who wrote or acted in the movie thanks to the company accounting practices that manage to show no profits after some enormous fees are added to the actual production costs. Return of the Jedi is just one example of many where one of the main characters is not receiving royalties in 2016.
