I posted these videos on RogueOne’s thread, for the sake of the current conversation regarding Nando v Movies, here are some initial attempts to remove Vader and mentions of him until the corridor scene:

Please note I have noticed a small sound glitch that lasts a split second on these videos which has been address after uploading these clips.
