Apparently George Lucas made this change back in the day. Probably for the 3D version that was cancelled when production for the new movies began pre-production.
This is the worst version, IMO. Even worse than the ’97 version. The new dialogue completely messes with the flow of the scene and while it’s less obnoxious that Greedo shoots in the ’11 version, it’s even more obvious in the ’19 version than the ’97 version.
Greedo not only shoots first but he utters “MACLUNKEY” at Solo before trying to kill him. How many more times can Lucasfilm continue to shit all over what was once one of the coolest scenes in Star Wars?!? I leave you with this…
To follow up on the word “MACLUNKEY,” apparently it’s a phrase that was used from The Phantom Menace where pod racer Sebulba said the same thing to Anakin ”Annie” Skywalker before the race. It means something along the lines of ”This will be the end of you.”
