It’s kind of weird that the movie that establishes Vader as Luke’s father (albeit perhaps a clone thereof or something) also features an extreme uptick in him Force-choking officers to death.
I blame George Lucas & Larry Kasdan reacting to the mild-mannered Vader of Leigh Brackett’s draft, where he dismisses officers who fail him with mild reproofs like “Leave me, you incompetent idiot.”
Replacing the (bad) dialogue with something much more frightening (telekinetic strangulations) was the right move.
I wish the deleted scene from RETURN OF THE JEDI made the final cut, the one with Vader almost killing the cheeky little sh*t officer that prevents him from seeing the Emperor.
