who did the voice of yoda in empire strikes back
Frank Oz Oz is also known as the performer of Jedi Master Yoda from George Lucas' Star Wars series. Jim Henson had originally been contacted by Lucas about possibly performing Yoda. Henson was preoccupied and instead suggested Oz to be assigned as chief puppeteer of the character, as well as a creative consultant. Oz performed the puppet and provided the voice for Yoda in The Empire Strikes Back (1980), Return of the Jedi (1983), Star Wars: Episode I – The Phantom Menace (1999), and Star Wars: The Last Jedi (2017).[18] Oz also provided the voice of the computer-generated imagery (CGI) Yoda in Star Wars: Episode II – Attack of the Clones (2002) and Star Wars: Episode III – Revenge of the Sith (2005). The conversion to CGI was met with some criticism among fans, but Oz himself said that was "exactly what [Lucas] should have done."[19] Oz had a great deal of creative input on the character and was himself responsible for creating the character's trademark syntax.[20] Oz returned to voice Yoda in Disney's Star Tours–The Adventures Continue attractions[21] and in the Star Wars Rebels episodes, "Path of the Jedi" and "Shroud of Darkness."
Darth Vader Darth Vader was portrayed by bodybuilder David Prowse in the original film trilogy, and by stunt performer Bob Anderson during the character's intense lightsaber fight scenes.[10][37] Lucas originally intended for Orson Welles to voice Vader (after dismissing using Prowse's own voice due to his English West Country accent, leading to the rest of the cast nicknaming him "Darth Farmer").[38] After deciding that Welles's voice would be too recognizable, he cast the lesser-known James Earl Jones instead.[39][40] Jones initially felt his contributions to the films were too small to warrant recognition and his role was uncredited at his request until the release of Return of the Jedi (1983).[10] When Jones was specifically asked if he had supplied Vader's voice for Revenge of the Sith—either newly or from a previous recording—Jones answered, "You'd have to ask Lucas about that. I don't know".[41] The character has also been voiced by Scott Lawrence and Matt Sloan for several video games. Hayden Christensen and Gene Bryant alternately portray Vader in Revenge of the Sith.[42][43] During the production of Revenge of the Sith, Christensen asked Lucas if a special Vader suit could be constructed to fit his own body, rather than have a different actor don one of the original sets of Vader armor worn by Prowse.[44] Brock Peters provided the voice of Darth Vader in the NPR/USC radio series. Both Spencer Wilding[45] and Daniel Naprous portrayed Vader in Rogue One (2016), with Jones reprising his role as the character's voice.[46]
