Origins and Production
Genesis of a Story
I Swear was born from both a personal and cinematic impulse. The film’s subject, John Davidson, first came into public view decades earlier as the star of the 1989 BBC documentary John’s Not Mad. That film – itself groundbreaking in its time – introduced broader audiences to the lived reality of Tourette syndrome, particularly forms that include coprolalia, the involuntary outburst of obscene language. Kirk Jones, a British filmmaker known for blending heartfelt emotion with nuanced social perspective, saw in Davidson’s life not just a historical episode, but a universal story about resilience, identity, and human dignity.
By choosing to dramatize Davidson’s life rather than merely document it, Jones’s project underscored the artistic ambition of engaging viewers emotionally and ethically with its protagonist’s world. This decision set the stage for a narrative that is powerful on both human and cinematic levels.
Filming and Cast
Principal photography took place in and around Glasgow in 2024. The production team – including cinematographer James Blann, editor Sam Sneade, and composer Stephen Rennicks – crafted a visual and auditory world that blends realism with expressive depth. The film’s structure is predominantly linear, tracing Davidson’s life from childhood in the 1980s through young adulthood and later into his recognition as a public advocate.
The casting choices anchor the film in both dramatic credibility and emotional clarity. Robert Aramayo, known for his work in The Rings of Power, stars as the adult John Davidson, while Scott Ellis Watson portrays Davidson’s younger self. The ensemble supporting cast includes Maxine Peake as Dottie Achenbach, a former mental health nurse and key emotional ally; Shirley Henderson as Heather Davidson, John’s mother; and Peter Mullan as Tommy Trotter, a community worker who plays a formative role in Davidson’s self-acceptance.
Taken together, these casting decisions enriched the film’s capacity to explore complex emotional terrain – from pain and shame to humor and solidarity. The actors’ performances became one of the film’s most remarked-upon strengths among critics and audiences alike.
Narrative and Thematic Structure
A Story of Understanding Through Time
The narrative arc of I Swear follows Davidson from his early adolescence, when tics first disrupt his life, through the profound repercussions these symptoms have on his schooling, family relationships, and self-image. In the 1980s Britain where the story begins, Tourette syndrome — especially its more visible symptoms — was poorly understood both medically and socially. Davidson’s early experiences are marked by exclusion and prejudice; his peers, teachers, and even his own family struggle to understand him, often responding with fear, denial, or outright hostility.
This early material is rendered with unflinching honesty that avoids voyeurism or sentimental simplification. Instead, it places audiences in the uncomfortable emotional proximity of a young person isolated by forces he cannot control, and communities unprepared to accommodate difference. The film depicts moments of brutal misunderstanding — physical punishment by educators, ridicule by classmates, and rejection by loved ones — alongside scenes of Davidson’s internal confusion and growing self-awareness.
Jones uses these early decades not just as backdrop but as commentary: the era’s limited medical knowledge, social stigma toward disability, and cultural silence around neurological difference compound the protagonist’s suffering. Thus, the film imbues what might otherwise be an intimate coming-of-age story with broader social and cultural critique.
Transformative Relationships
As Davidson enters adulthood, I Swear shifts toward relational and communal themes. Key among these is his connection with Dottie Achenbach, whose compassion and steadiness mark a contrast to the hostility Davidson has previously faced. Her presence in the narrative signifies not rescue but recognition — an invitation to see Davidson not as an outsider but as a person whose experiences and insights matter.
The character of Tommy Trotter further expands this theme. Trotter’s willingness to work with Davidson despite his unfiltered outbursts emphasizes that inclusion is not just ethical but practical: communities function better when they adapt to accommodate difference rather than expect conformity.
These relationships anchor the film’s emotional center, charting a progression from isolation to interconnection. They make clear that Davidson’s “success” is not merely personal resilience but emerges through collective affirmation and support.
Humor, Pain, and the Title’s Double Meaning
The title I Swear operates on multiple levels. On its surface, it evokes the involuntary swearing that characterizes coprolalia — a symptom of Tourette syndrome that most audiences associate with the condition. But the phrase also encapsulates broader themes: Davidson’s repeated affirmations of his own intentions, identity, and worth; the promises he makes to himself and others; and, in a larger sense, the human insistence on being understood.
This duality informs the film’s tonal balance. While moments of humor — often rooted in the absurd unpredictability of tics — elicit laughter, they are never cheap or exploitative. Rather, they remind audiences that human suffering and joy frequently coexist, and that laughter can be both a release and a revelation. This tonal balance has been remarked upon by critics as one of the film’s great strengths, enabling audiences to experience Davidson’s world with empathy rather than pity or discomfort.
Critical Reception and Public Response
Critical Acclaim
From its premiere at the 2025 Toronto International Film Festival to its wider theatrical release later that year and into 2026, I Swear garnered considerable praise. On review aggregator Rotten Tomatoes, it achieved a 100% critics’ rating early on — a testament to its critical reception. The consensus highlighted the film’s emotional depth and Aramayo’s compelling performance, noting its elegant balance of humor and pathos.
Many reviewers emphasized that the film avoids both sensationalizing and sanitizing its subject matter. Instead, it provides an unvarnished look at Davidson’s experiences while maintaining a humane, reflective perspective. Critics from publications such as The Times, The Guardian, and the Financial Times praised the film’s authenticity, its compassionate eye, and its ability to prompt audience reflection on prejudice and inclusion. The ensemble performances, especially by Aramayo, Peake, Henderson, and Mullan, were singled out as deeply moving and technically superb.
Accolades and Awards
In early 2026, I Swear achieved notable recognition at major awards ceremonies, including the BAFTA Film Awards, where it received multiple nominations and wins. Among these were awards for Best Casting and the EE Rising Star accolade for Robert Aramayo, whose acceptance speech emphasized honoring Davidson’s lived experience and advocacy. The film also won Outstanding British Film, situating it as a landmark British production of its year.
The BAFTA ceremony itself sparked public discussion when Davidson, present as a guest, experienced involuntary outbursts — a reminder that the film’s subject was not an abstraction but a living person. Host Alan Cumming explained the involuntary nature of Tourette’s symptoms to the audience, which in turn prompted broader media conversation about visibility, representation, and respect.
Audience Reactions
Audience responses have been equally multifaceted. Many viewers reported deep emotional engagement, noting the film’s ability to move between anguish and joy with fluidity. Social media discussions and online forum threads reflect a blend of admiration for the storytelling and introspection about disability representation on screen.
Some discussions, particularly among members of the Tourette’s community or disability advocacy circles, explored the ethics of having an actor without Tourette syndrome portray Davidson. These conversations weigh authenticity against the practical and ethical complexities of casting, with many concluding that the film’s portrayal — informed by Davidson’s own input and lived insights — ultimately serves as respectful and impactful representation.
Cultural Impact and Interpretive Themes
Representation and Awareness
One of the most significant achievements of I Swear is its impact on public awareness of Tourette syndrome. Prior to the film’s release, many people outside medical or activist circles understood the condition only through caricature — particularly its coprolalic aspect. I Swear challenges this reductive view by contextualizing the symptom within a fuller human life story, exploring the condition’s emotional, social, and relational dimensions.
By telling Davidson’s story not merely as a “disease narrative” but as a human journey with dignity and complexity, the film contributes to broader cultural understanding and destigmatization. Schools, community organizations, and public forums have referenced the film in discussions about inclusion and disability rights, further extending its reach beyond the cinema.
Ethics and Artistic Responsibility
The discussions surrounding I Swear’s casting and depiction of neurological difference illuminate critical ethical questions about representation in media. Should roles depicting specific conditions ideally be played by actors who share those conditions? Does the act of portraying a real person’s lived experience inherently involve tensions between authenticity and artistic craft?
While opinions vary, many advocates have noted the film’s respectful collaboration with Davidson himself and its commitment to conveying his voice with integrity. This has positioned I Swear as a case study in how films can engage ethically with subjects whose lives and identities intersect with societal misunderstanding and marginalization.
