Trivia

He and Kenny Baker are the only actors to have a role in all six George Lucas-involved Star Wars movies, and he himself is the only actor to feature in all nine films of the Skywalker Saga.

As C-3PO, he has planted his 'metal' footprints in the courtyard pavement of Mann's (formerly Graumans's) Chinese Theatre.

As C-3PO, he has the first line in the first Star Wars episode released (Star Wars: Episode IV - A New Hope (1977)) and the last line in the last Lucas-helmed movie (Star Wars: Episode III - Revenge of the Sith (2005)).

He has played the same character (C-3PO) on nine different series: Sesame Street (1969), The Muppet Show (1976), Star Wars: Droids (1985), Star Wars: Clone Wars (2003), Star Wars: The Clone Wars (2008), Star Wars: Rebels (2014), Star Wars: Forces of Destiny (2017), Obi-Wan Kenobi (2022) and Ahsoka (2023).

Is one of three actors, along with Mark Hamill and Billy Dee Williams, to reprise their same roles from the original Star Wars trilogy in the NPR radio dramatizations of the trilogy. However, Daniels is the only one to appear in all three NPR serials; Hamill and Williams were unavailable to reprise in "Return of the Jedi" (1996).

Mel Blanc was the one who ultimately suggested Daniels for the voice of C-3PO.

Is the first actor to appear in both a Star Wars film and a Lord of the Rings adaptation, by having played C-3PO in Star Wars, and voicing Legolas in Ralph Bakshi's The Lord of the Rings (1978). Other crossover actors include Paul Brooke (the Rancor keeper, who also voiced Grima Wormtongue in the BBC radio adaptation), Sir Christopher Lee (who played Count Dooku and Saruman), Marton Csokas (who played Celeborn and was the original voice of Poggle the Lesser), Kiran Shah (who played an Ewok, and was the scale double for Elijah Wood and Sir Ian Holm), and Bruce Spence (who played Tion Medon and the Mouth of Sauron).

Ironically enough, he was never a science fiction fan. The only science fiction movie he ever saw in a theatre was 2001: A Space Odyssey (1968). He was so dissatisfied with the movie that he walked out after only ten minutes and demanded his money back.

In addition to playing C-3PO in all nine episodic Star Wars films, he played the role in the NPR radio dramatizations of "Star Wars" (1981), "The Empire Strikes Back" (1983), and "Return of the Jedi" (1996).

Born on the exact same date (and in the same country) as fellow actor Alan Rickman.

He has played the same character (C-3PO) in films released in five different decades from the 1970s to the 2010s: Star Wars: Episode IV - A New Hope (1977), Star Wars: Episode V - The Empire Strikes Back (1980), Star Wars: Episode VI - Return of the Jedi (1983), Star Wars: Episode I - The Phantom Menace (1999), Star Wars: Episode II - Attack of the Clones (2002), Star Wars: Episode III - Revenge of the Sith (2005), Star Wars: The Clone Wars (2008), Star Wars: Episode VII - The Force Awakens (2015), Rogue One: A Star Wars Story (2016), Star Wars: Episode VIII - The Last Jedi (2017) and Star Wars: Episode IX - The Rise of Skywalker (2019).
