The AMP suit is seen in the movie as a helpful mech for heavy construction, and later as part of a destructive military weapon against the Na'vi. In all cases, the performance of the AMP suits was entirely motion-captured. The upper half of the AMP suit was put onto a motion base driving movements based on the motion capture. For this motion capture, there were no legs or arms on the AMP suit. John Rosengrant says they sometimes removed the glass for the shot, such as when actor Stephen Lang, who portrays Colonel Miles Quaritch in the film, is inside of the AMP suit piece, reacting and reciting his lines. "It really grounds it, and it feels really real," Rosengrant said. Building a practical machine and using CG to further elevate it is what makes standout hybrid characters. To make the AMP suit functional from a practical aspect, the team placed tracking dots all over the model to help the animators line up and reconcile the information. Then, the animators added the arms digitally so there was free fluid motion tied into the cockpit base, though the movements of the base itself were captured from the unit moving around on the hydraulic motion control system. The result on screen was a hybrid blend of techniques, Rosengrant says. These included: complete CG, complete static models, an interactive working prop with lights inside, as well as a hybrid combination where the machine is functioning hydraulically on a motion base with an actor riding in it, and the arms and legs added digitally.' has been replaced with 'The AMP suit is seen in the movie as a helpful mech for heavy construction, and later as part of a destructive military weapon against the Na'vi.
