A Monster Calls

  • Movie

In A Monster Calls, Liam Neeson voices the CGI monster who helps a young boy cope with loss through the fantastical stories he weaves. These stories are depicted as animated vignettes in the film, and a new VFX video from Glassworks Barcelona reveals how some of the movie magic was conjured.

While the footage mostly focuses on these fairy tales — involving kings, princes, and dragons — it also highlights some of the VFX that went into the creation of the titular monster. Also seen is the young Lewis MacDougall, who plays Conor, the boy at the heart of the story.

“After all this time, and despite the research work done, it’s also very complicated for us to put in words what this experience has meant,” the video description reads, in part. “This project enabled us meeting wonderful artists, with whom we had never collaborated before; people more fantastic than the tales we all made possible. Thanks everyone for putting all your love and a little bit of your life in these stories.”

Glassworks promises to release a longer cut of the visual breakdown, but for now, what the video above.

A Monster Calls also stars Felicity Jones, Sigourney Weaver, and Toby Kebbell. The film will open in select theaters on Dec. 23 before going wide on Jan. 6.
