Where some games will rely on just a vocal performance from an actor and leave the animators to fill in the rest, Elizabeth was a composite of two performances. Courtnee Draper provided the voice to Elizabeth while Heather Gordon provided her physicality through motion capture. This practice isn't uncommon, but rarely is such care paid to making both of the performances sync up. Heather confessed that she really tried to blur the personal lines between her and Courtnee's performance to make it as authentic as possible.
