In 1997, a movie featuring John Travolta and Dustin Hoffman was released. I recommend this movie to all my journalist friends. It is a must watch.
In 1997, it showcases the effects of post-truth news. They hadn't coined that word yet then. But most of the things you will see in the movie are surreal.
However, it is not a futuristic film. Whatever is depicted is an extrapolation of sorts from the Lady Diana's death which happened in Aug 1997. In the years leading up to it, there were discussions of possibility of papparazi getting killed while chasing her. Sadly, she ended up in that accident.
But it tells you of power of media, the responsibility and the effects.
