text: A 2015 Spanish documentary by filmmaker Marcos Cabotá, entitled I Am Your Father, detailed Prowse's then life and his blackballing by Lucasfilm, which the documentary suggested was unjustified. The leaks featured in the documentary originated from a technician working on the films.
  Partnership with Jayce Lewis
  Prowse became friends with Welsh musician Jayce Lewis when the latter was a teenager, after they met at a science fiction convention. At the convention, Lewis recalled learning that Prowse's son, whom he later met after a performance, was also a drummer. On their shared musical interest, Prowse identified himself as "a music fan for years, going from big band jazz, trad jazz, modern and progressive."
  The two became business partners with Prowse taking on a management and public relations role. He was also featured in the music video for "Shields" on the album Orderart. On 1 October 2015, Lewis created a mini-documentary entitled The Force's Mouth, which gave Prowse the opportunity to hear himself voicing Darth Vader's lines with studio effects applied for the first time.
  Personal life
  Prowse was married from 1963 to Norma Scammell and was the father of three children. He was a supporter of Bristol Rugby Club. He lived in Addiscombe, Croydon, in south London from 1963.
  Prowse publicly declared his support for the United Kingdom Independence Party in the 2009 European Parliament election: "I've looked right and left and right again and the only party I can safely vote for is UKIP."
