Tourette's syndrome remains a hugely misunderstood condition – and the stigma around it can make life with Tourette's an isolating one. Raising awareness about the realities of life with Tourette's is something that Scottish activist John Davidson set out to do after being diagnosed with the condition in his teens – and now, Kirk Jones' powerful biopic I Swear is bringing Davidson's work into the spotlight.
Starring an endearing, charismatic Robert Aramayo as Davidson, I Swear offers a warm, heartfelt retelling of the activist's life, from his youth in the Scottish Borders, to his adult years that see him embracing the condition and becoming a powerful voice in the Tourette community.
The film has already received a number of accolades, including six BAFTA nominations, including Outstanding British Film, Best Original Screenplay (Jones), and Best Leading Actor (Aramayo). Aramayo took home the Critics' Circle Breakthrough Performer of the Year Award following his performance in the film.
Aramayo won both Best Leading Actor for I Swear and the EE Rising Star Award at the 2026 BAFTAs. Accepting the former, Aramayo tearfully said, “I absolutely can’t believe this. I honestly cannot believe I have won this award. Everyone in this category blows me away.”
It's a vital film that will open your eyes to a widely misunderstood condition – and, hopefully, lead to more tolerance and empathy for those with the syndrome. A heart-wrenching, honest drama, it's also a touching portrait of a powerful man that will stick with you for months, if not years, after watching. It is, in other words, a must-see.
Here's how you can watch the film now.
Five stars you've definitely seen before.
A portrait of activist John Davidson, I Swear offers a new, intimate look at the stigma that surrounds Tourette's syndrome – and what life with the condition really looks like.
As Davidson, Aramayo portrays how the tics associated with the condition can lead to a life of isolation and miscommunication. He is given the strap at school by teachers who don't understand his symptoms. He is horrifically beaten outside of a club after yelling at a girl in the street. He is ostracised at almost every turn. He struggles to find employment. He winds up in jail.
But it also offers powerful moments of hope and recognition, too. When he eventually begins connecting with other people with Tourette's, there is a moment of long-awaited release and freedom that will move any viewer.
Finally, Davidson is recognised for his activism, receiving an MBE – and inadvertently shouting “fuck the queen!” moments before it happens.
I Swear came out on 10 October in the UK when it was released in cinemas across the country. The film was later released on DVD on 29 December.
I Swear is available to rent on Curzon, Apple TV and Prime.
I Swear stars Robert Aramayo as the adult John Davidson, while Scott Ellis Watson plays the younger version of the role.
Also in the case are Peter Mullan, Maxine Peake, Shirley Henderson and Adam McNamara.
