A Monster Calls

A Monster Calls is a 2016 dark fantasy drama film directed by J. A. Bayona and starring Lewis MacDougall, Sigourney Weaver, Felicity Jones, Toby Kebbell, and Liam Neeson. Featuring a screenplay adapted by Patrick Ness from his own 2011 novel of the same name, the film follows a boy grappling with his mother's terminal illness who is visited and told stories by a giant anthropomorphic yew tree.

The film rights to Ness' novel were acquired by Focus Features in March 2014, after which he was hired as screenwriter and Bayona signed on as director. Jones was cast that April, Fanny joined the film in May, and the rest of the main roles were cast by September. Principal photography began on 30 September, with filming taking place primarily in West Yorkshire, Derbyshire, and Lancashire in England, as well as in Bayona's native Spain.
