Inside a Netflix recording studio off Sunset Boulevard, director Kyung Sok Kim, associate producer Anastasia Barbato and engineer Yoav Litman scanned a big screen as they replayed a scene from an episode of “All of Us Are Dead.” They subbed in audio from an English recording made by two voice actors in a sound booth nearby.Â
The trio carefully watched to be sure the English words matched the mouths of the Korean actors and the performance was authentic to the script.
