This is the original made-for-TV movie that introduced the Max Headroom character.
I was thinking about posting a video describing the Max Headroom hack but then figured this community is focused more on the fictional aspect of the cyberpunk genre than the real world events so I'll stick with the movie.
I can't remember if I've seen this movie, I've watched the series... low key would dig a reboot. Gonna have to make time to watch this soon.
