Right at the end of AOTC there are a couple of seconds of footage of Bail on a balcony dropping his head and striking his fist on the rail in defeat.
It’s a sunset scene with red lighting and so it would be perfect to repurpose as the moment when he sees the apocalyptic destruction wave roll across Alderaan towards him. It also has the classic iconography of a King on their balcony surveying their Kingdom, so even first time viewers ought to be able to make the implied connection that this Royal-looking person is Princess Leia’s father.
Thats the exact shot i used in the deleted scene. But i was never going to add that scene into the movie. It was done just for fun and i won;t be adding anything like that in the HD version.
