Thanks for posting the list, VF.  With all the voice talent responsible for multiple characters, pulling this together must have been quite a project.  I know nothing of sound engineering, so please cut me some slack on what may appear to you an infantile question; when recording something like 52 that has such a huge number of characters, do you record individual voice actors/characters seperately, then mix everything together, or do you have multiple actors in the recording studio at the same time?  The benefit of that would seem to be interplay between the talent enhancing the pefformances, but the downside would seem to be when a voice actor has to, in effect, have a conversations with themselves when their characters in the script interact - trying to slip into and out of character during a running conversation must be a tough assignment.  Give us a feel for how a recording session may run....Thanks.

The voice actors are usually recorded seperately in a vocal booth and mixed together is post production. There are times when they record multiple actors at the same time, like crowd scenes.
