The directors of this documentary, who are Star Wars fans from his childhood, have done a good homage to actor Dave Prowse, the man behind the mask of Darth Vader.
Through several interviews with people directly involved in the making of the original Star Wars trilogy the film discovers the reasons that affected the relationship between Prowse and Lucasfilm after finishing the shooting of the original trilogy. Fortunately the film provides different opinions about this matter.
Last but not least, their homage also extends to other great film actors that played evil roles behind a mask.
