Oh, whilst the Vader fight isn’t going to be changed (although with unlimited resources and two stunt doubles…? LOLs) one thing I would like to see changed if at all possible is Obi-wan referring to Vader as “Darth” as if it was his first name and not title!
It was his first name when they were filming… You can think about it as if he’s mocking the title, that’s what I do.
