After a second viewing I now realise what bothered me about the Emperor scene. When viewed side-on the Emperor looks like he is mostly a single still frame, animated by the static and jitter of the poor signal. It’s most apparent in the final shot where he appears frozen with his mouth open for a few seconds before closing it towards the end.
It’s still a great improvement over the blu-ray version where they re-shot Ian McDiarmid looking nothing like the ROTJ Emperor who apears only months later in ‘Retun’.
Most definitely! Ian McDiarmid looked like he had just walked off the set of Revenge of the Sith. Funny that.
