8. 100 YEARS OF SOLITUDE, BY GABRIEL GARCIA MARQUEZ (1967)
Status: Not in development
It’s one of the most influential novels of the 20th century, yet no one in Hollywood has ever really attempted to turn Gabriel García Márquez's classic into a film. Taking place over a century and spanning multiple generations of the Buendía family, 100 Years of Solitude revolves around the formation and eventual devastation of the fictional town of Macondo.
There are countless characters, endless symbolism, and plenty of historical allusions to real-life Colombia here, and any director would have to have nerves of steel to take this adaptation head-on. However, with the right script, this story could be one of the best ever put on screen.
