Jackson, a longtime fan of the comics, had used motion capture in "The Lord of the Rings" and "King Kong"; he suggested that a live-action adaptation would not do justice to the comic books and that motion capture was instead the best way of representing Hergé's world of Tintin. A week of filming took place in November 2006 in Playa Vista, Los Angeles, California, on the stage where James Cameron shot "Avatar". Andy Serkis had been cast, while Jackson stood in for Tintin. During the shoot, Cameron and Robert Zemeckis (director of "The Polar Express", another motion-captured animated film) were present. The footage was transmitted to Weta Digital, who produced a twenty-minute test reel that demonstrated a photorealistic depiction of the characters. Spielberg said he would not mind filming it digitally because he saw it as an animated film, and reiterated his live-action work would always be filmed traditionally. Lead designer Chris Guise visited Brussels to see the inspiration for Hergé's sceneries.
