No Actors Were CGI’d in the First Game
The 456 contestants seen in the first game were actually portrayed by 456 actors. While most shows would have simply CGI’d people to give the appearance of several characters, the director wanted to keep everything as realistic as possible, so he opted for using real actors and sets as much as possible so that the audience would get a real performance. He even made sure that the tense moments throughout each episode were as close to realistic as possible.
