A view of Andy Serkis, right, with a rough model of Gollum.
"I remember the first day of putting on a motion capture suit, and seeing a very rudimentary, grey-shaded version of Gollum," Serkis recalled. "You know, when I was lifting up my right hand Gollum was lifting up his right hand. And it was just like a magic mirror. I was sort of looking at it and thinking, 'Wow.'
"And literally after a few days of doing that, I remember going into the restroom and looking in the mirror and Gollum was there! It really was very bizarre."
