The books were adapted by Tony Grisoni, who did a heck of a job on the Fear and Loathing in Las Vegas adaptation, with Julian Jarrold (Becoming Jane) to cover Nineteen Seventy-Four, James Marsh (Man on Wire) to tackle Nineteen Eighty, and Anand Tucker (Shopgirl) to helm the final installment, Nineteen Eighty-Three. (Nineteen Seventy Seven will be split amongst the three other features.) The films will be brought together into a television series, with a theatrical release to follow (one that hopefully includes overseas distribution).
The tale of the Yorkshire Ripper -- Peter William Sutcliffe -- is pretty grisly. (Check that link for the whole story.) He was convicted in 1981, and while he is still alive, he has gotten a bit of the "eye for an eye" treatment from fellow criminals.
