http://movieweb.com/person/benedict-cumberbatch/Sherlock star Benedict Cumberbatch was recently interviewed and discussed his experience filming the role of Smaug the dragon in Peter Jackson's The Hobbit: An Unexpected Journey.
Here the actor explains how he had to free himself from his surrounding enviroment while shooting with a sensor suit.
"It's very freeing, once you put the suit on and the sensors. I've never felt less encumbered, actually. And you have to be. You have to be free. You just have to lose your shit on a carpeted floor, in a place that looks a little bit like a mundane government building. It was just me as well, with four static cameras and all the sensors. Then the boys at Weta work their magic."
He goes on to explain when you might see the deadly dragon rear its head.
"I think my eye will open at the end of the first film, and then you'll get the rest of me in the second."
