'Lord of the Rings' star Andy Serkis also pops up in Hall H audience
Andy Serkis asks a question
Sneaky hobbit! Peter Jackson wasn't the only surprise guest on hand: Gollum himself, actor Andy Serkis, made it all the way from Middle Earth to ask a question or two from the audience.
Serkis, a motion-capture veteran after "Lord of the Rings" and "King Kong," plays the role of Captain Haddock in "The Adventures of Tintin."
The film also stars Daniel Craig, Jamie Bell and Simon Pegg.
