The Hollywood Reporter has news that Michael Douglas’ Further Films is developing a feature film based on author Shirley Jackson’s 1962 novel ‘We Have Always Lived in the Castle’.

‘Castle’ revolves around the Blackwood family — primarily of sisters Merricat and Connie and their uncle Julian — who have been forced into seclusion after the mysterious lethal poisoning of several of their family members six years earlier. Merricat is the younger sister, caring for the agoraphobic Connie, while the ailing Julian increasingly is in the grip of his own obsessions.

The plot is further complicated by the arrival of a dubious long-lost cousin who seeks to secure the family’s fortune.
