I have a very close friend who is a brilliant clown, and I always wanted to do a show with him. So I did one year at La MaMa Theatre. I had not done stilts before that show, and I had about two weeks to learn how to do that, and they were just made with off-off Broadway money. The ones that I had in Rogue One were made by [Industrial Light & Magic]. So they were really easy. They were made with actual prosthetic feet on the bottom. They were athletic, in a way. I could run in them. There was a bounce to them that I could use.

I consider theater, this is a vacation for me from LA, I sort of view this as I get to have this vacation and during my vacation I get to work on acting. It's like an acting class. And if I go too long without doing a play, I just feel empty. Like approaching a role, I feel like the pool is very shallow, like I'm drawn from it. So I need to come back and do a play, fortunately I've been able to, every couple of years.

C-3PO is flappable [in Star Wars]. [Kaytoo is] very unflappable compared to C-3PO, who is just flapping all over the place.

Because I'm CGI, [John Swartz] gave me a role of an Imperial pilot in one scene, so I had a day where I was on camera dressed as a black suit and a little cap that they wear.

Those are always fun characters to play, the ones who are stupid but speak with authority.

I actually oddly have done another robot motion capture. I did Sonny in I, Robot.

[ Gareth Edwards] never wanted to force anything that wasn't true. He's very much an actor's director, and it was loose.
