Leftover aotc material?
Yes, the scene where Obi-Wan brings Luke to Owen & Beru was actually filmed during AOTC shooting.
Actually, I believe I read that they re-shot the characters for this shot on green screen during RoTS filming anyway. IIRC, they did it to change who was holding Luke. Could have also been for better visual continuity for Ewan, though he had his hood up, I think.
edit: I would have never guessed I was in this thread based on the topic. I must’ve just clicked it like a robot.
