I used to watch this show all the time. It only ran for two seasons because it was too ahead of it’s time. Did you know there’s an full archive of these shows? https://archive.org/details/max-headroom-complete

As I know Max Headroom wasn't an AI but an actor (Matt Frewer) was masked out and "played" in front of a bluescreen. Just the creators wanted if it has looked like as a CGI 🙂
