Most of us are big Muppets fans here at Cinematical, so it's with a heavy heart that I report the following: Frank Oz, the voice of Yoda, says CGI has rendered the practice of good old-fashioned Muppetry extinct. Whilst shilling the Revenge of the Sith DVD in the Chicago Tribune yesterday, Oz expressed some nostalgia for the days when operating the wise little guy involved four people performing "hard, sweaty, down-and-dirty work in the pit." Yoga was digitally recreated for the prequels, and now, says Oz, "the actual puppet can't work." How sad: somewhere there's a Yoda puppet, sitting at home on a ratty couch, smoking cigarettes and drinking beer and watching Maury and cursing George Lucas for being such a futurist. The four guys pulling his strings are also pissed.
