Ah, that makes sense then.
Not having done much special effects works, I was curious as to how it’d be done on anamorphic film.
I noticed, and it’s odd.
Disney considered it a significant enough part of him that he’s seen having it in Rebels, a good five years before the OT. I have to wonder how many years have to pass before he’s allowed to replace parts of the wrong colour.
Being that they used both Vistavision and Technirama, and I assume a third camera for non effect shots, I wonder how hard it was to mix the negatives, seeing that to my knowledge you’d have three different anamorphic scales for the shots.
