I wanted to show this clip from The Rover and talk a little bit about free rigs. There's a lot of free animation rigs out there and we see them over and over in animation tests. Often moving & acting in very similar ways. But check this clip out, it features an almost unrecognizable Robert Pattinson. It's not really a physical transformation, like some actors undergo, but its more of an acting transformation. It's in complete contrast to how we've normally seen him in other movies. (cough cough Twilight) His mannerisms, movements, pacing, delivery. Think about this when you're animating on a free rig. How can you make it new, unique, something we haven't seen before.
