David Prowse, who portrayed Darth Vader physically in most scenes of the original Star Wars trilogy, was not interviewed for this documentary, and is only briefly featured through archive footage. This was due to his strained relationship with Lucasfilm and George Lucas in particular (due to an incident for which the actor was unfairly blamed as a result of a miscommunication), which also led to Prowse subsequently being banned from attending official Star Wars fan conventions.
This feature-length documentary is featured on the 4-Disc Star Wars Trilogy DVD set, released in September of 2004.
Perry King, who screen-tested for the role of Han Solo, played the role in the 1981 NPR radio dramatization when Harrison Ford was unable to do so because of his commitment to I predatori dell'arca perduta (1981).
