There’s plenty of stuff to dislike about the SE without citing Luke screaming the Emperor’s scream as he falls in Cloud City, one of the few (the only?) changes George actually reversed in later re-revisions of the OT.
It’s weird to think that George offered the Episode I director’s chair to other people (Zemeckis, Ron Howard, Darabont et al), all of whom turned him down and said he should direct it himself.
