‘Iron Boy’ Review: A Beautifully Hand-Painted Coming-of-Age Story with a Dash of Magical Realism

TIFF: Former Pixar animator Louis Clichy delivers a lovely film about a boy in an iron corset and his family's struggles to keep their French farm afloat.

A young boy keeps tilting his head seemingly uncontrollably, which causes him to lose his balance. Sometimes it’s kind of funny, like when he simply cannot sit straight during a photoshoot for the school yearbook. But when one such incident causes the boy to lose control of his father’s truck and crashes it, it leads to the boy’s parents taking him to a doctor, who diagnoses him with scoliosis and orders him to wear a rigid iron back brace. This is the fate of the titular Iron Boy (the film’s French title, however, is simply “Le Corset”), an 11-year-old named Christophe. His story is a beautifully hand-painted coming-of-age tale that is economical in its visuals, but as expressive and emotive as any big-budget animated film.

“Iron Boy” is set in rural France, but not the gorgeous hills and vineyards of the Bourgogne region. Instead, the film takes place amidst the rather flat landscapes of the Beauce region southwest of Paris, a place dominated by enormous skies and vast fields of grain, an empty horizon only occasionally broken by power lines. Here, life is far from idyllic or calm. It is hectic, productive, and — as soon as Christophe’s rigid and emotionally-stunted father joins a cooperative to try and save his farm — exploited by industry. Here, speaking about your feelings (let alone showing them) is a big taboo, and introspection is non-existent. And yet, Louis Clichy, who got his start as an animator at Pixar, working on “Wall-E” and “Up” before returning to France to co-direct two entries in the huge “Asterix” franchise, makes “Iron Boy” hugely emotive in the subtlest ways. Reserved gestures and seemingly trivial or understated expressions carry a huge emotional weight. Christophe rarely smiles in the movie, for instance, so when it does, it’s significant. 

What Christophe does show, however, is anger. When he lets his boiling anger explode, he tilts his head, causing the world around him to tip over alongside him, people flying around, objects dropping like it’s a scene from “Twister.” Christophe’s little smirks as he sees himself remaking the world as he sees fit when he is pushed too far evokes Katsuhiro Otomo’s “Akira.” The film treats these outbursts of emotion with a dash of magical realism, a fantastic representation of a young boy’s repressed emotions.

The visuals in “Iron Boy” reflect this state of repressed feelings, by using watercolor backgrounds with vast skies that emphasize the negative space in the frame, the pockets of unfulfilled expression just waiting to be filled with imagination. If the backgrounds represent Christophe’s world, simple, big, untouched, then the Chinese inkbrush lines transform that emptiness into expressions, with straight lines looking fluid, faint expressions carrying huge emotions. The sparse yet wildly expressive linework and watercolor washes are reminiscent of Chiara Malta and Sébastien Laudenbach 2023 film “Chicken for Linda!” another film whose simple visuals packs an expressive and emotional punch.

It is this combination of naturalism and cartoonish expression that makes “Iron Boy” stand out even amongst European animated films. The film employs mostly non-professional voice actors, including Clinchy’s own son (who plays Christophe), and the director would often record the lines on location, to give the performances a less constructed sound than if they were done in the clear confines of a studio. It makes the story feel quasi-documentary in its approach, an intimate and deeply personal story of a boy searching for more than what life has offered him, restrained by a physical affliction that nevertheless allows him to live an extraordinary life.

While he’s away from the farm and trying to get used to his new reality, Christophe discovers a passion for music, thanks to his local church organ player who opens his eyes and ears. Seemingly for the first time, Christophe begins to live, to truly care about something. But, as Christophe’s father learned as a boy, and as his brother recently learned, farm life and family expectations tend to clash with what we envision for our futures. “Iron Boy” packs an emotionally complex story about fulfillment and dreams. Christophe’s father may be stern and emotionally stunted, but the film never reduces him to just a villain. Instead, it finds immense sympathy in the lives he might have given up in order to tend to the family farm, in his struggles to adapt to a quickly-changing agricultural landscape, and his struggles to connect to a son with whom he can’t fully communicate. 

Meanwhile, Christophe is desperate to leave the farm life behind, as he finds in music a world that genuinely excites him, but is oblivious to the clear struggles his family is going through. It is only when the family starts slowly, subtle pay attention to what each other is going through, to the unspoken pains, the unfulfilled dreams, that they can begin to overcome their strained relationships, to set things straight, as the corset is meant to do to Christophe’s spine.

Grade: B+
