Skin tone was another primary focus, as animators studiously considered, yes, what it would mean to be someone with green blood coursing through his veins. Their determination: The "meat" would be darker as a result, not brighter. Accordingly, their Hulk appears olive in most scenes and, fleetingly, almost slate gray. "We wanted to incorporate him more into our environment, to make him feel like he's right there and you could touch him," says visual effects supervisor Kurt Williams, whose team used software engineered for the fantasy menagerie of "The Golden Compass" as a springboard for rendering the Hulk. "We needed to approach him like a CG [computer graphics] human, not a creature."
I wonder if they'll use the same philosophy when they make up Zachary Quinto as young Spock in the upcoming Star Trek movie (probably not).
