This is a bit of a trick question regarding Palpatine's Empire Strikes Back appearance, where he looks noticeably different from the Ian McDiarmid version in Return Of The Jedi. Well, that's because the actor or actress was completely different. That's right, American Actress Marjorie Eaton played Palpatine in the theatrical release. Whilst there was significant makeup work done, her voice didn't make the cut. Much like James Earl Jones taking the role of Darth Vaders voice, the Royal Shakespeare Company veteran Clive Selsby Revill voiced the Emperor. In 2004, The Empire Strikes Back features Ian McDiarmid in his Revenge of the Sith makeup.
