I like comedies, and my brain sort of spins in that direction. So I'm really happy to say there were several smartass comments that come from me [on Star Wars].
R2-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.
It's just like they approach things on every movie I've worked on, very much as if it was a live-action movie. The character you're playing, even though he's a rooster and is really stupid, you approach it in the same way you would approach Hamlet, which is exactly how I approached it. But they give you the circumstances. "You're on the boat. You didn't expect to be here. You just climbed in a boat to maybe sleep. You don't even know why you climbed in the boat. You're really that dumb.
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.
