The film follows thirteen-year-old Conor O'Malley, who is dealing with his mother's sickness, school bullies and a yew tree in his backyard that turns into a monster that tells him strange stories. Over a period of time, the monster's stories give him the tools to come to terms with the truths of life. Liam Neeson is portraying the monster.
Juan Antonio Bayona is directing the film, which Patrick Ness adapted from his children's fantasy novel with the same name. Focus Features is targeting a October 14, 2016 release.
