The sprawling, hugely influential, and highly acclaimed book series has never been made into a film or film series or TV show and spans as rich and dense a mythology and characters as The Lord of the Rings and Game of Thrones and could very likely be as successful as a long-running TV or film project - especially in the hands of HBO which would give it proper financial and creative support together with Warner Bros. capable TV studio.
The fascinating story set far into mankind's future when humanity has spread out across the galaxy inhabiting millions of worlds (without ever finding extra-terrestrial life) spans across several millenia and dozens of characters.
Mathematician Hari Seldon invents psychohistory which can broadly "predict" human behaviour and behavioural patters on a massive scale, and he constructs a plan to shorten the predicted new "dark age" of the Galactic Empire by setting up the "Foundation".
The mesmerising story, filled with major twists and dramatic, unexpected turns, concludes with a few books detailing a highly adventurous journey of an intrepid group trying to find the origins of humanity, apparently a place called Earth.
According to The Wrap, the Foundation TV series has been in development for the last several months between HBO, Warner Bros. TV and Jonathan Nolan.
