Watching one of the preview recently provided for 4K80 I noticed in the “Lando system” scene that Threepio, who’s shut off in the background, is not a stand-in puppet but actually Daniel’s in costume. Looking really closely I can see him shift slightly as he breathes. Seems kinda odd to have Daniels put on (or keep on) the costume only to have him sit still in the background, though this might have to do with the fact that as the Falcon detaches from the SD, the camera tilts a little and Ford and Fisher both move as if the cockpit itself actually tilts, and Threepio likewise shifts a bit in his seat.

I also noticed that a bit of the view out the cockpit is cut off in the next shot. At the far right of the cockpit windows, near Threepio’s head, there’s a black area where there should be more of the view of the SD and the space trash.
