 To create the "art nouveau" animation style effect the production  team was looking for, all of the games possible paths and actions  (over 800 scenes) were filmed with 50 live actors wearing special  makeup against a bluescreen. The footage was then input into a  computer and, using a specially designed process, was processed and  turned into black and white line drawings. From there, the footage  was meticulously hand painted frame by frame (over 40,000 frames  total) to create the final effect.
