Diagnosed with Tourette's syndrome at a young age, John Davidson struggles with a little-known condition that alienates him from his peers and that few people have ever witnessed.
Written and directed by Kirk Jones, I Swear is a poignant and grounded biographical drama chronicling the real-life journey of Scottish Tourette syndrome activist John Davidson. Set against the backdrop of 1980s and 1990s Scotland—a period when Tourette syndrome was heavily misunderstood, neglected, and stigmatized—the film strikes a delicate balance between unflinching dramatic realism and sharp, organic humor.
At the core of the film is Robert Aramayo’s career-defining lead performance. Aramayo captures the physical intensity of Davidson’s involuntary tics and coprolalia alongside the profound emotional isolation that accompanied them, delivering a layered depiction rooted in genuine vulnerability. Maxine Peake offers tremendous supporting depth as Dottie Achenbach, grounding the narrative with warmth, compassion, and emotional stability.
Rather than reducing neurological illness to a comedic trope or sentimental melodrama, Jones maintains narrative integrity by confronting the ignorance and ostracization Davidson faced daily. By blending uncomfortable truths with heartfelt perseverance and well-timed levity, the film delivers a compelling tribute to human resilience and empathetic storytelling.
