Some stories come in gently, like someone holding their breath for too long. Some hit you in the chest and won’t let go. I swear it’s the latter.
It’s the real voice of John Davidson, a Scottish youngster who was called “crazy” in the 1980s because of something he couldn’t help: his Tourette’s condition. This isn’t a clean drama. It’s not cooked. It is real. And it will be unforgettable in the hands of filmmaker Kirk Jones.
I Swear develops its heartbeat—and its power—from moments you can’t un-see, like the risk of public disgrace, family distress, and teenage terror.

There hasn’t been any news of a streaming release yet, which makes it seem like this compelling drama was made for the big screen. It’s a chance to sit in the dark with strangers and feel the heavy truth of one young man’s life together.
A Journey Behind the Camera and Inside the Mind
Kirk Jones is back to directing after being away for almost ten years. He is known for comedies like Nanny McPhee, but he looks at this biopic in a very different way: raw, immersive, and very personal.
I Swear is based on the true story of John Davidson, a teenager from Galashiels, Scotland, who became one of the UK’s most well-known Tourette’s advocates. People didn’t know much about tics back then, so John’s obvious tics were treated with derision, judgement, and medical confusion. This movie doesn’t just show that; it challenges you to dwell with it.
The setting, which was filmed in Glasgow and rural Scotland in the middle of 2024, shows how raw and lonely Britain was in the 1980s. There is stigma in the hallways of schools. Family living rooms are full with silence and stress. And at the centre of it all was John, twitching but not broken.
Cast to Honour a Life Lived
Robert Aramayo leads the cast, and many early viewers say this is the best performance of his career. Aramayo is known for his roles in fantasy and drama. He used an almost systematic approach, living with John in his hometown to pick up on every little thing he did, like every tic and breath.
British powerhouses are joining him:
- Maxine Peake plays Dottie Achenbach, a friend who looks past the diagnosis.
- Shirley Henderson plays Heather Davidson, John’s mother. Her love is both strong and weak.
- Peter Mullan plays Tommy Trotter, a character who gives John something very rare: understanding.
Every performer gives their character weight and honesty, which keeps this biopic authentic to the man behind the story.
Watch the Full Trailer
The trailer gets right to the heart of the matter. A teenage teenager is twitching in a school hallway. Staring faces. Whispers getting louder. Then there was silence, save for the tic that interrupted it. It hurts. It is true. It’s so human it breaks your heart.
The images are rough and realistic, with handheld cameras and natural lighting to show how John sees things: constantly exposed, always watched, and never really in control.
Why I Swear Will Hit Hard
- Uncompromised Truth: John Davidson was the executive producer, therefore every scenario is based on real life, not dramatic licence.
- Dedication of the Actor: Robert Aramayo’s preparation wasn’t simply physical; it was also emotional, mental, and very respectful.
- Contemporary Representation: I Swear is both contemporary and timeless in a world that is finally waking up to neurodiversity.
- Cinematic Realism: The rough and tough Scotland of the 1980s isn’t just a setting; it’s a character that affects every encounter.
