Don't blame Lucas, blame the folks at ILM for showing George that it could be done 100% in CG. Just like Jurassic Park, Spielberg was ready to use animatronics until Muren, Williams, Dippe proved otherwise. or Rob Coleman's team showing that a CG Yoda was feasible. without these guys we'd be back to puppets and models and the good ol' handpainted matte painting. damn you ILM!
