LUKE'S GHOST

This is an odd little thing that you might never have noticed. In the establishing shot of the Lars homestead courtyard on the morning that Luke has gone to chase after Artoo, you can see a semi-transparent still image of Luke in one of the doorways. Also, the Treadwelll droid jumps to the other side of the courtyard in the next shot when Uncle Owen enters.
IN NEED OF FIXING SINCE: ?

Very interesting. One of the reasons many of you haven't noticed this before is that this error was introduced in '97, "Luke's ghost" never appeared in the original film. Maybe they got rid of it in post for the original film, and when going back to the negative for the '97SE this error got introduced? the "ghost" remain throughout the sequence, so the shot is clearly made up of one static frame. Hard to tell if this shot in the original film was made of a series of the same single frame though.
