Netflix is expanding its lineup based on Stephen King's works. According to Deadline and Variety, the streaming service has picked up the rights to In The Tall Grass, a novella written by the horror maestro and his son, Joe Hill, who's also an acclaimed horror author. Netflix is reportedly turning the novella into a feature film, which will star James Marsden (Westworld, X-Men) and will be directed by Vincenzo Natali known for Cube and Splice. The story revolves around a pair of siblings on a cross-country road trip who find themselves unable to leave a field of tall grass after venturing into it to save a little boy crying for help. Unfortunately, it's too early in the film's development to say when it will become available on the service.
