Talking about the flip shots, that last shot of the storm troopers running out and shooting at Leia is flipped also the shot before she goes out the door.
Their gun holsters are on the other side of their body. I actually think this makes more sense to be un-flipped as they are coming out from where leia was standing previously where the window was. I don't see any damage to unflipping that one but perhaps there is.
I also had a thought today about this whole "look out", "Behind us" SE addition which you won't find on any lists on SE change lists and what not. But If Ady likes this addition as it's in the clip we got treated to. Should that not be C3PO saying those lines instead? I could handle those words then.
@Bingowings I was hoping to see R2 coming from the door as leia runs too, but this is obviously not possible unless the team have an R2 unit. But I think they may get one at some point
