I have been looking at the matte paintings of Bespin recently.

I noticed there was some swapping around on the buildings particularly the Slave 1 landing Platform. What is curious about it is that it must have been re-done a few times as the buildings when the falcon takes off on the left seemed to have been originally planned for Slave 1. I know they are gone in Revisited (i do miss the Spire on the right though.. sorry) but it is worth knowing that it was swapped about and put to Plaform 327 which is a bit odd.

And then I stumbled across yet another Joe Johnston story board... The Storm troopers Run out the door, again they never made it in to the next shot. Is it Just Joe's Imagination getting a bit carried away?

Nevermind... one of the Patrols might pick them up :)

I dont think there is any more missing or adjusted elements I found four from existing footage in the film discounting planned scenes never constructed. 2 laser fire 1 shot missing tie fighters and the troops on the platform. Not too many and adjusted would seem to count for 3 of them Laser and tie fighters to suit the story.

EDIT:

forgot about the deflection lasers from Han shooting at Vader but you did something about that one that counts in the missing pile. And cool you did that.

I just looked at it a bit more in depth... The shot of the Storm trooper running was moved to a later point in the sequence to make it appear as if the Storm Troopers were not meant to have reached the Platform in the take off shot because they are missing and not filmed.... But you will notice Lando's last Laser bolt is fired before he retreats and hits the wall before the storm trooper runs giving up the shots proper original order in the sequence. As who can fire the shot that hits the wall if they are all already on board the falcon... Another puzzle solved.
