I'm only about 4 years behind on that one, but caught up on all of the rest.
Being mostly based on the nerd/geek community, most of these have been talking about Rogue One, and what come across universally is how good K-2SO voiced and motion-captured by Alan Tudyk is. Something I'd seen that just makes me cackle is the following video with Tudyk relating how Anthony Daniels reacted to his portrayal:
But back in one of the podcasts, someone brought up a comparison C-3PO as a nervous wreck who spouts things in fits of cowardice while K-2SO says things because he has no filters.
And then I had a geek-piphany.
- K-2SO says things because he has no filters.
- K-2SO's loss of filters is because he was reprogrammed from being an Imperial droid to being given free will (of a sort).
- Some of the things the K-2SO spouts freely are the odds of an event's failure.
- C-3PO regularly spouts off the odds of an event's failure, in the original trilogy.
- C-3PO was reprogrammed after the end of Revenge of the Sith to blank his memory.
Now, sure, this is all easy to explain afterwards, but did the writers of Rogue One see that pattern, and write that in?
Some may scoff that anyone would be that detailed. First off, to those people, have met Star Wars geeks? Second, check out this bit from the Rogue One soundtrack by Michael Giacchino that fits so well against John Williams' "Imperial March".
And then think back to how cool it was to learn about Hans Zimmer using the Edith Piaf bit in all of the levels in Inception.
Yeah, you can never go deep enough.
