The actor who played Darth Vader in the Star Wars series has revealed he has dementia, which is why he is not in the upcoming film.
David Prowse told the Mirror he would have loved a part in Star Wars: The Force Awakens, but feared he would struggle to remember his lines because of his diagnosis.
While he is on tablets to fight the condition, he said: "I don't feel I've improved at all. Sometimes I can't remember things I did yesterday. That worries me more than not remembering something 20 years ago."
The 79-year-old actor opened up about his struggle with the degenerative disease for the first time shortly after the teaser trailer for the new film was released - and admitted he would have loved a cameo. David starred alongside Harrison Ford, Mark Hamill and Carrie Fisher in the first three movies of the hugely popular series.
