Anthony Daniels (born February 21, 1946 in Salisbury, England) is an actor best known for his role as the droid C-3PO in the "Star Wars" series of films made between 1977 and 2005. It is interesting to note that Daniels and Kenny Baker (who played R2-D2 in the series) are the only actors credited as playing the same role in all six of them (although apparently Baker is only in the closing scene of Episode II and does not actually appear in Episode III at all).

Aside from playing the fussy droid in all six movies, Daniels also voiced C-3PO in a radio serial based on the original trilogy and the animated series Droids and Star Wars: Clone Wars. He also had a cameo in the nightclub scene of Star Wars Episode II: Attack of the Clones as Lieutenant Dannl Faytonni, the man in blue, who reacted after Obi-Wan strikes the bounty hunter Zam Wesell early in the film. Faytonni can also be seen at the Galaxies Opera House in Star Wars Episode III: Revenge of the Sith. Daniels was the voice of Legolas in The Lord of the Rings animated film. He crops up intermittently on British TV in various dramas.

Daniels has been politically active in the United Kingdom, but he has kept his politics and his professional life completely separate.

Quoted in the Examiner, Kenny Baker described Anthony Daniels as standoffish. Baker and Daniels have been feuding for three decades. Daniels, now 59, was never friendly to the other actors in the film, either. "Anthony doesn't mix at all," says Baker. "He keeps to himself."
