Patrick Ness ("Class") adapted his own acclaimed young-adult novel for this dark, emotionally resonant and visually stunning 2016 fantasy film about 12-year-old Conor (Lewis MacDougall), whose lonely life with his cancer-stricken mother (Felicity Kendal) is changed by a massive, ancient tree creature (Liam Neeson via motion-capture animation), who tells the boy three stories. Sigourney Weaver and Toby Kebbell also star.
