Quick trivia: Is anyone else noticed that luke's head appears behind R2 D2 when the falcon first get shot and lights are fading off and on? He appears in 3-4 frames and i suggest that he should be removed from that shot.

I know I'm a little late, but... yes, someone else noticed ;)

59. There's a shot of R2 and 3PO in the curved seat on the Falcon. Look closely behind Artoo - for a few frames at the end, a head (probably Luke) appears. I've painted it out.
