George Lucas reveals why Star Wars' Yoda speaks differently. First introduced in the 1980 blockbuster Star Wars: Episode V - The Empire Strikes Back, Yoda, voiced and puppeted by Frank Oz, is an important figure in both the original trilogy and the prequel trilogy as the one who trained Luke Skywalker and the Jedi before him. Known for popular quotes such as "Always in motion, is the future," the way Yoda talks is central to what makes him memorable.
