or every dancer into animator :D

The movement of the character is quite mechanical, (for instance the jiggly effect on the limbs with very sudden stops in movement). It's probably easier to animate, then to find an actor who's capable of perfectable incorperating theses in his performance.

Mocap is pretty difficult and time consuming, actually. Much more interesting for lifelike movements like Gollum's, not so much for a robotic puppet like this
