VFXWorld has a story up about Zoic Studio’s work on the new episodic drama Dollhouse airing on Fox. Most of the work is basic Greenscreen effects, with the exception of the “mind wipe” scene.
The one consistent visual effects trope in Dollhouse is the mind wipe process, in which an “Active” is put in a chair that literally zaps their memories into a recorder that’s archived by the Dollhouse proprietors. Audiences get to see what that process looks at from Echo’s perspective.
