So Ryan Reynold is Detective Pikachu in the upcoming Pokemon film, but he's not only voice-acting for Pikachu, but doing the motion capture. So what do you call the act of doing both? Is there a word for it?
The person who does the voice and facial capture (and occasional full motion capture) for a completely CGI-rendered character is still call the actor for the role. There is, as of yet, no special term for this combined, as it's generally going to be the same person.
At least for the scenes that show detailed characterization, such as dialogue and facial expressions. For the more physical action scenes, stuntmen (and women, of course) are used. These are collectively referred to as mocap actors.
