David Prowse was done a complete injustice
David Prowse was done a complete injustice by not being used in the death scene where they used a different actor completely. I remember the first time I saw Vader's human face I was totally disappointed and thought "who is that?" Uncanny considering, that at that time, I had never seen David Prowse yet but knew who I was seeing was not the man who had been in the Vader costume in all those films. I really think that the filmmakers screwed up hiding by using Sebastian Shaw
(who I am sure was a great actor) instead of Prowse.
