This is reverent. This is Star Wars, damn it. You don't screw around with it. The things that were improv'd or added that developed on set weren't huge departures as far as storyline or anything like that goes. They just were clarifications in character or, at the best moments, they spoke to the moment in the story in a way that, at least with Kaytoo, tended to be funny.
Alan TudykC-3PO is flappable [in Star Wars]. [Kaytoo is] very unflappable compared to C-3PO, who is just flapping all over the place.
Alan TudykR2-D2 is like that, but I think because he doesn't speak actual words, his jokes don't land. It's really a hindrance. And the same with BB-8. But Artoo is a lot stronger.
Alan TudykI wrote and directed and acted in it and produced it, every job I have since that - and Star Wars included - I look at it completely different now. Now that I've seen how it gets made, I can appreciate the jobs that people are doing, and it's also become a different learning experience for me to work on things because I'm watching pros at the top of their field do their jobs and just picking up on their tricks and all of their expertise and stashing them away in my brain.
