E! News has obtained an exclusive behind-the-scenes clip The Hobbit: An Unexpected Journey Extended Edition, which was released on Blu-ray Nov. 5, and in it, sir Ian McKellen is taking his cues from fellow cast member Andy Serkis, who plays Gollum and also doubles as a second unit director on the production.
And if you ask Serkis, the legendary British actor was none too thrilled to be receiving direction while acting in front of a green screen.
