Cool find Bon, I wonder which costume's Nic has hired?! the medieval knight I could see too, or an astronaut or all those other characters he has mentioned he used to enjoy playing as a child! ( and indeed why ever should it stop as an adult?! ) but that would definitely be a costume not a disguise..unless of course he has mastered the art of time travel as I suspect...
Being an actor means you get to play dress up for a job though which is fun!
