Cartoon Saloon, the studio behind “The Secret of Kells,” “Song of the Sea,” and “The Breadwinner,” returned in 2020 with what could be their best film, a rousing, lyrical, gorgeous adventure called “Wolfwalkers.” This beautiful piece of work has echoes of other art from classic fairy tales to Studio Ghibli films about man’s relation to nature like “Princess Mononoke,” but it also develops its own powerful voice.

Set in 1650, “Wolfwalkers” takes place against the backdrop of the English colonization of Ireland. Oliver Cromwell sends a hunter named Bill Goodfellowe (Sean Bean) to a remote outpost that has seen wolf attacks as the city grows into the woods around it. Bill’s duty is to hunt and kill the wolves, but his daughter Robyn (Honor Kneafsey) is eager to join him on his daily duties, frustrated by being left behind in a city that doesn’t really want her father or her there. Robyn is an outsider, her father forced into duty in a way that makes her a target of ridicule by local kids.

Robyn sneaks away and follows her father into the woods, discovering that the legends spoken of in town of a wolfwalker is true. She meets Mebh (Eva Whittaker), a girl who has a wolf form that is independent of her while the human Mebh sleeps. She also has healing powers and control over the vicious wolfpack that has been tormenting people. Mebh is waiting for her mother to return from her wolf form, hoping that she will then lead the pack to a safer place.

“Wolfwalkers” unfolds almost entirely through hand-drawn animation that more often echoes watercolor art that has come to life than what modern audiences expect from cartoons. It has a mesmerizing beauty with so much refined attention to detail. The colors splash across the screen and the line detail sometimes feels like it’s purposefully calling attention to the fact that somebody drew this.

With this beautiful visual language, Tomm Moore and Ross Stewart complete what has been called their “Irish Folklore Trilogy” with a story that’s thick with adventure and tension. This is not a cautious, reserved fairy tale like what people typically expect from that genre. It’s really an action movie as Robyn and Mebh seek to save a way of life and keep their people safe. And, of course, there’s the subtext underneath about empowerment, colonialism, and man’s relationship with nature. There’s so much going on in every frame.

If there’s a flaw in “Wolfwalkers,” it’s length. It feels like there’s a masterpiece of a 95-minute movie buried in this 105-minute one. Some of the scenes go on just a tad too long and some ideas are repeated one time too many. While the movie doesn’t feel that long because of the joy of just experiencing it, it could have been slightly tightened up.

Many people return to the Studio Ghibli films at different points in their life and get different things from the best of them. “Wolfwalkers” will have a similar staying power, playing with a different energy in childhood, adulthood and old age. (SD-Agencies)
