Here, Jessica is supposed to be climbing up on one of the worms. On set, she was merely running on a treadmill by the side of the dummy worm. Note the grip's foot, to catch her if she slipped! We had to add a moving ground, blowing sand (matching her running speed), and to top it off, a bit of camera shake.
|It took some very complex rotoscoping and compositing, but Cecelia did a great job.|
