fishmanlee, im guessing just one cut with no story changes.
ChainsawAsh, it wouldnt make sense "then perhaps she will" since Leia shouldnt be force sesitive.
Back to ESB:R
Since Vanderios is going to change the melting metal from the last part of the lighsaber battle between Luke and Vader.
There should be noticed many places on that lighsaber fight where Vader hits something and at least for a moment have it "melting", and be carefull that the places they hit the handrail wasnt broken before the lightsaber hit it.
Specially, there is one moment, when Luke and Vader are just coming out from that door that Vader hits with his lightsaber the wall (clearly) There should be a scratch...
