Angelina Jolie recently started work on Robert Zemeckis's animated film Beowulf. To ensure that every nuance of Angelina's every facial expression was recorded, over 150 sensors were strategically glued onto Angelina's face. Around 50 more sensors were added to Angeline's body suit to capture all of her movements from all angles. Each of these 200 sensors on Angelina's face mask and body suit recorded and layered a 3-D digital skin to use as a base for animators to work with. This process was developed by Sony Pictures Imageworks and is known as performance-capture (an amped-up version of motion-capture that uses sensors to digitally record an actor's every movement - even the slightest smile).
