It's closer to just acting in a film because it was a six-month commitment. We got to fly all over the world.

Kaytoo [from the Star Wars] is more even-keeled. And he's a badass. He comes from the Empire, and he's a security droid. Some people call him an enforcer droid. He has the ability to enforce things. That was what he was built for. He's tall. He has an intimidating frame.

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

[Diego Luna Cassian] quite a smartass, and I really appreciate smartasses. He used to make fun of me for the stupid backpack I wore. There were a few situations where I couldn't [wear the stilts]. [When] I was on a cliffside or running in water and stuff like that, I had to wear this backpack with a telescoping head that came off the top, and it was really stupid looking.

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.

Reading is a heady thing. You can be into the action of someone's thoughts and take a whole trip down someone's ruminations while seconds tick by in the world that they're in, but you can't really do that in film. Some films can, but not too much.

[I'm] a huge defender of clowns around the world.
