<P> Oz explained why he decided on leaving the Muppets in a 2007 interview: </P> <P> "One was that I was a dad, I have four kids . The reason was that I was constantly asked to do stuff . And also, I'd done this for 30 years, and I'd never wanted to be a puppeteer in the first place . I wanted to be a journalist, and really what I wanted to do was direct theatre and direct movies . So it was more a slow progression, working with Jim, but I felt limited . As an actor and a performer, you always feel limited because you're not the source of the creation, and I wanted to be the source . I wanted to be the guy and give my view of the world . And if I screw it up, I screw it up, but at least I tried . And as a director, what you're really showing is you're showing the audience your view of the world...I've always enjoyed, more than anything else in the world, bringing things to life, whether it's characters or actors in a scene or moments in movies . I've done so much with the puppets, that I'd always wanted to work with actors ." </P> <P> 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). 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 ." Oz had a great deal of creative input on the character and was himself responsible for creating the character's trademark syntax . Oz returned to voice Yoda in Disney's Star Tours--The Adventures Continue attractions and in the Star Wars Rebels episodes, "Path of the Jedi" and "Shroud of Darkness ." </P> <P> Inspiration as a filmmaker came to Oz upon a viewing of the Orson Welles film Touch of Evil (1958), the director told Robert K. Elder in an interview for The Film That Changed My Life: </P>
