Based on the bestselling novel, this fantasy drama adaptation is directed by J.A.
Bayona and written by Patrick Ness. Young Conor (Lewis MacDougall) struggles to deal with his mother (Felicity Jones)'s terminal illness, the heartless grandmother (Sigourney Weaver) he must stay with, and the bullying he receives at school from Harry (James Melville).
Gripped by guilt, anger and fear, Conor is given support from a quite unlikely source: a drawing of a great, ancient tree monster (voice of Liam Neeson) that comes to life.
The monster visits Conor at night to tell him stories and help him come to terms with his difficult situation.
With the monster at his back, Conor faces his problems directly with courage and conviction.
