who played the emperor in star wars episode 6
Ian McDiarmid In the 2004 re-release of The Empire Strikes Back, a brief scene between Darth Vader and a hologram of Emperor Palpatine was updated to include McDiarmid. The Emperor was originally voiced by Clive Revill for that scene, and visually portrayed by Marjorie Eaton.[14][15][16] With this addition to The Empire Strikes Back, McDiarmid has now appeared in every live-action film version in which Palpatine appears.
Ian McDiarmid After a minor part in the film Dragonslayer, McDiarmid was cast by George Lucas in Return of the Jedi as Emperor Palpatine, the main villain. Sixteen years after appearing in Return of the Jedi, he reprised the role as the character's younger incarnation of Senator Palpatine and Sith Lord Darth Sidious in the prequel films: The Phantom Menace, Attack of the Clones, and Revenge of the Sith. The prequels had him play two faces to his character; he re-created his diabolical interpretation of Palpatine from Return of the Jedi when playing Darth Sidious, the Chancellor's Sith alter ego, but created a pleasant, charming character in Palpatine's public persona.
