Benedict Cumberbatch has described working with motion capture as 'freeing'.
The actor is part of the ensemble cast for The Hobbit trilogy which will see him take on the role of dragon Smaug.
The actor has brought the character to life using motion capture and he admits that it was a process that he really enjoyed.
Speaking to Total Film the actor said: "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 s**t 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."
Cumberbatch lines up alongside Martin Freeman, Ian McKellan, Richard Armitage and Andy Serkis in the movie while Peter Jackson returns to the director's chair.
It has been a busy year for the actor as he has also filmed Star Trek Into Darkness where he will play the baddie.
The Hobbit: An Unexpected Journey is released 14th December.
