Anamation Lead Jon Mummery on Perfect Dark Zero's Storyboards:
"For the cutscenes we would start by taking the script and storyboarding it out. Then we would create a small animatic of the storyboard to lay out various camera angles and see what works in the background. Once happy with that, we would go ahead and motion capture as much as we could, and for more tricky moves we would simply animate them the traditional way. Once we have the mocap data we go about editing it and speeding bits up, often adding a layer of animation over the top of the mocap to make it loop or move a certain distance as desired by the design. I would say that about half of the content in the cutscenes have motion capture and half of the content is traditionally animated. "
