Mary Reilly is a 1996 film which retold Robert Louis Stevenson's Strange Case of Dr. Jekyll and Mr. Hyde from the perspective of Jekyll's housekeeper. Midway through shooting, Jim Henson's Creature Shop was contacted to provide a motion-control rig. For the transformation sequence, as star John Malkovich went through the motions of transitioning from Jekyll to Hyde, a motion-control camera captured the actor's movements; the Creature Shop's rig was designed to copy the head and upper torso movements and be programmable frame by frame.
