C-3PO is a humanoid robot character from the Star Wars franchise who appears in the original trilogy, the prequel trilogy and the sequel trilogy. Rebuilt by Anakin Skywalker, C-3PO was designed as a protocol droid intended to assist in etiquette, customs, and translation, boasting that he is "fluent in over six million forms of communication". Along with his astromech droid counterpart and friend R2-D2, C-3PO provides comic relief within the narrative structure of the films, and serves as a foil. Anthony Daniels has portrayed the character in all ten Star Wars cinematic films released to date, including Rogue One and the animated The Clone Wars; C-3PO and R2-D2 are the only characters to appear in every film.
Many people remember C-3PO being entirely gold plated throughout the original Star Wars Trilogy, although the movies now show C-3PO with a silver leg. The claim is that the character never had a silver right leg in the original versions of these movies.
Evidence for this particular Mandela Effect seems almost entirely anecdotal, with many posts on the subreddit about the topic.
Potential ExplanationsThere are many explanations for this particular Mandela Effect. Anthony Daniels, the actor behind C-3PO, has also made statements about this particular Mandela Effect.
"He always had silver, but one of the issues was the silver leg actually always reflected other things, it would reflect the gold leg, and it would reflect in the desert, so it acted more as a mirror, and even the stills photographer, John Jay, came up to me one day and said, 'Why are you wearing a silver leg today.' Now, he was the stills photographer...and he hadn't noticed. So we went one stage further, or J.J decided, let's make it noticeable with a red arm"- Anthony Daniels (C3PO)
