Okay, I promised some BESPIN 'flipped' shot shenanigans a while back, so here they are (I've included a few extra shots from the sequence they appear in to place them in context) -
When we cut-away from the Luke/Vader 'duel' to this 'escape' sequence, Chewbacca's 'bandolier' is correctly slung over his left shoulder and the 'sack' is by his right side....and only C3PO's right arm is attached....

....and when we immediately cut to this shot below, things are still the correct way round....
2.


....but after 'close-ups' of Chewie, R2, and Lando, when we then cut to this shot below....it turns out that it has been 'flipped'. It's a reversal of the same set and background that is seen later on in the movie, as shown below in shot 21. However, in addition to this, it looks like the actors have been reversed too....as the security guard's 'gun holster' is on his wrong side (compared to all the other guards in the movie), and the nearest woman's 'buttons' are on the wrong side too. Women's garments are usually designed to button-up on the opposite side to men's ones, and I'm assuming the actress was given a 'female' top to begin with....

....and then everything is the correct way round leading up to this shot below....

....and when we immediately cut to this shot below, things are still the correct way round (as Leia is still holding her gun the same way during it)....

....but when we immediately cut to this shot below....it turns out that this has been 'flipped' too. Chewie's bandolier/sack and C3PO's attached arm are suddenly on the wrong sides now (and R2's details and the Stormtrooper's costume are reversed too)....

....but when we immediately cut to this shot below....it turns out to be another one that's been 'flipped'. The costume detail on the Stormtrooper's 'knees' and black 'side holsters' are on the wrong sides now....
