While the facial animation and hair were incredibly challenging, the Beast's ragged cape proved troublesome, to say the least.
"If you were to ask a visual effects person, 'What is the absolute most difficult pain-in-the-ass costume that you could possibly think of?' this would be it," jokes Port.
However, Digital Domain was able to work closely with costume designer Jacqueline Durran -- whose team built the cape for real -- in order to provide detailing for the digital version. The final CG cape incorporated a raft of simulated materials, from bones, feathers, silk, string, and extra bits of hair.
