Lucasfilm has released a new featurette for the film that focuses on K-2SO and some of the magic that went into bringing this wonderful character to life. There’s a good amount of cool behind-the-scenes footage showing Tudyk running around in his motion capture suit and talking about the character saying that he’s the anti C-3PO. Tudyk looks like he was having the time of his life while shooting Rogue One.
This featurette doesn’t do this droid justice. He was, without a doubt, the best part of the movie. His lines were spot on and timely. I didn’t think I could like a droid more than R2 and BB-8, until now.
