Here's a scene from Mortal Kombat vs. DC Universe that I worked on at Midway Games. Joker has some newfound abilities and decides to "call out" the Batman.
I did the facial animation for Joker and Batman. I also had to go in and heavily handkey Joker's motion, exaggerate his timing, poses and add a lot of flourishing movements to his hands and fingers (which were non-existent in the mocap data).
Variety magazine even gave props to Joker's performance. Click here for the article.
Mortal Kombat vs DC Universe is available now for the PS3, X360 and Wii. Do check it out. If anything, it is a fun game to play.
