Here’s a better link and a nice bedtime story by the man himself: http://www.youtube.com/watch?v=qOuF2yh1lKU&t=47m15s
Just a thought, but with C3PO reverting back to his golden arm during his last shot in TFA, I wonder if it will stay that way or not when he’s seen again in the next movie?
If it stays gold without any explanation whatsoever, then that might leave a lot of people who don’t know it’s ‘backstory’ scratching their heads…whereas if it’s back to red again without any explanation, then it will remain looking as if it’s been a continuity mistake…
But there could be a nicely poignant moment to be had in the next movie, if C3PO actually summarizes the reason he wears it sometimes…and I’m kinda hoping that this happens now!
Anyway, back to the…er…‘speculation’ about what ROGUE ONE is going to bring.
