Several R2-D2 models were built for the original "Star Wars" films; one that was remote controlled and rolled on three wheeled legs, and others which were worn by English actor Kenny Baker and walked on two legs. Deep Roy (who also doubled Yoda in several scenes), served as Baker's double, in both "Episodes V" and "VI"; providing stunts and filling in when Baker was unavailable. The original props for "Star Wars Episode IV: A New Hope" were designed by John Stears and built by Stears' team and Peteric Engineering. The revised fibreglass droids used in The Empire Strikes Back were built by Tony Dyson and the White Horse Toy Company. The radio controlled R2 was operated by John Stears in "A New Hope", Brian Johnson in "The Empire Strikes Back" and by Kit West in "Return of the Jedi".
