I hadn’t heard about the missing frame. Where is it? Is it really any worse than R2’s moving restraining bolt or the duplicate R5 or the Jawa with human arms?
Are you sure you want to know about it? Once you see it, you can’t look at the scene anymore without seeing it…
On Hoth, when Han’s on top of the Falcon getting it ready to evacuate, some rebel troops run by on the ground. Because the troops are fairly fast-moving, it’s easier to see if you focus on the troops and not on Han (not the normal way to watch that scene). A frame gets dropped right in the middle, not at a scene change or anything.
