Amazon have cancelled work on their planned television adaptation of Consider Phlebas, the first novel in Iain M. Banks' Culture series, after the Banks Estate decided not to proceed with the project.
Jeff Bezos himself, a huge fan of the Culture books, personally announced that Amazon were working on the TV show back in February 2018. Writer Dennis Kelly developed a treatment and series bible, but it seems that when it came time to sign the final deal, the Banks Estate decided not approve the option.
Banks wrote ten books in the Culture universe between 1987 and 2012: Consider Phlebas, The Player of Games, Use of Weapons, The State of the Art, Excession, Inversions, Look to Windward, Matter, Surface Detail and The Hydrogen Sonata. This is more of a common background for the books rather than in-depth series, with the books jumping backwards and forwards in time.
The Culture is a massive, multi-species, utopian civilisation spanning thousands of worlds and space habitats. The Culture finds itself pitted against various external and internal challenges and threats, which its agents and citizens find themselves having to deal with.
Iain M. Banks sadly passed away in 2013 and development of the TV show began after Amazon made overtures to his Estate. It appears no formal deal was signed, since the Estate has now decided not to proceed with the project.
None of Banks' SF work has been adapted to the screen, although several of his mainstream novels have been adapted for TV and film: The Crow Road, Complicity and Stonemouth.
Amazon has also passed on its adaptation of Neal Stephenson's Snow Crash, which has instead moved to HBO Max, whilst their planned take on Larry Niven's Ringworld also seems to have stalled. They also passed on a Conan the Barbarian TV show from Ryan Condal a couple of years back (Condal is instead now working on the Game of Thrones spinoff House of the Dragon).
Amazon do have some big SFF projects moving forwards, however, with a fifth season of The Expanse due to air before the end of this year, the first season of The Wheel of Time next year and The Lord of the Rings: The Second Age in 2022.
