During the "Storytelling in Video Games" panel at PlayStation Experience Until Dawn Creative director Raúl Rubio Munárriz showcased a video that included some really impressive facial animations and acting.

Munárriz mentioned that the key to achieve those expressiveness is to have really good actors. The script from the game is fairly huge, so the actors need not only to memorize it, but they also need to remember what emotion they left off with the previous line, that might have been acted at a different time due to the branches, and that can be challenging.
