The film 'I Swear,' now available on Netflix, chronicles the life of John Davidson, an advocate for Tourette syndrome awareness. The movie dramatizes his experiences with the condition, highlighting the public's frequent misunderstanding and the personal struggles he faced.
'I Swear' begins by depicting a moment of public controversy for Davidson at the 2026 BAFTA ceremony. As is characteristic of Tourette syndrome, he experienced an involuntary outburst, shouting inappropriate remarks. This incident, amplified by discussions around the BAFTA producers' decision to air the moment, brought Davidson's story to a wider audience and underscored the film's central themes.
The narrative flashes back to 1983, when a 13-year-old Davidson, portrayed by Scott Ellis Watson, first began experiencing uncontrollable tics and vocalizations, including expletives. This led to bullying at school, disciplinary action, and eventual expulsion. His personal life was further complicated by his parents' divorce and his own struggles with the condition, which led him to contemplate suicide.
Thirteen years later, the adult Davidson, played by Robert Aramayo, lives with his mother and takes medication that offers partial relief but leaves him feeling unwell. A chance encounter with an old friend introduces him to Dottie (Maxine Peake), a former mental health nurse who offers him compassionate support and encourages him to stop suppressing his condition. Under her care, Davidson is diagnosed with Tourette syndrome, and they begin a journey of education and self-acceptance.
The film then follows Davidson's life episodically through subsequent decades. It depicts his employment at a community center under a compassionate supervisor, Tommy (Peter Mullan), and further instances of public incidents and their consequences, including legal debates about Tourette syndrome and a severe assault. He finds community among others with Tourette and engages in organizing events to educate the public and their families about the condition.
Robert Aramayo's performance as Davidson has been noted as excellent, and Maxine Peake's portrayal of Dottie serves as a crucial catalyst for the film's emotional core. The film aims to use drama as a vehicle for education and advocacy, exploring the complex emotions associated with living with Tourette syndrome.
'I Swear' has drawn comparisons to a series of BBC documentaries about Davidson: 'John's Not Mad' (1989), 'The Boy Can't Help It' (2002), and 'Tourettes: I Swear I Can't Help It' (2009).
The film's approach to depicting Tourette syndrome, particularly moments involving involuntary outbursts, has been described as eliciting both laughter and reflection, illustrating the 'cognitive dissonance' of finding humor in difficult situations while acknowledging their inherent sadness. The movie ultimately seeks to foster empathy and understanding for individuals with Tourette syndrome.
