text: In 2008, he was one of the cast members featured on Justin Lee Collins's Bring Back...Star Wars. In the episode, Prowse commented that he had a dispute with Lucas after he allegedly leaked reports of Darth Vader's death to the press. Prowse had previously suggested that Darth Vader could be Luke Skywalker's father in a speech he gave to University of California, Berkeley, in 1978. However, this was shortly after the release of Star Wars and nearly two years before The Empire Strikes Back was released, and the script had not even been written at the time. Gary Kurtz, the producer of The Empire Strikes Back, said in the 2015 documentary I Am Your Father that Prowse's apparent plot spoiler was simply "a good guess."
  Prowse stated his contract for Return of the Jedi included a share of profits on the film, and although it grossed $475 million on a $32 million budget, Prowse explained in an interview in 2009 that he never received residuals for his performance. Due to "Hollywood accounting", the actual profits are sent as "distribution fees" to the studio, leaving nothing to distribute to others.
  In July 2010, Prowse was banned by Lucas from attending official Star Wars fan conventions. Lucas had given Prowse no reason, other than stating that Prowse "burnt too many bridges" between Lucasfilm and himself.
  In 2011, Prowse wrote and released his autobiography Straight from the Force's Mouth.
