From the very first Star Wars film in 1977, C-3PO has remained one of the most important and iconic characters in the entire franchise. Portrayed by Anthony Daniels, the protocol droid has appeared in almost every Star Wars film for over forty years, as well as several different animated and live-action series. Timid and fearful, C-3PO is one of the most beloved droids in Star Wars, especially when paired with his best friend, R2-D2. The character's popularity truly knows no bounds, with some fan theories even going so far as to position C-3PO as the narrator of the entire Star Wars saga.
