“I Swear” is based on the life of John Davidson, a Tourette syndrome campaigner who grew up with the condition in 1980s Scotland, at a time when it was little known and misunderstood.
A Bold, Human Introduction
“F–k the queen!”
This is a film that knows how to make an introduction. But it also knows when to be real. After a short, comedic opening, “I Swear” begins to masterfully tug at heartstrings. And it’s not fabricated. While showcasing the teenage years and adult life of John Davidson, the movie presents an inherent sense of relatability.
Through his uncontrollable vocal outbursts and movements, the film manages to put the audience inside John’s shoes. Some moments are uncomfortable — and they’re supposed to be. Rather than providing a glossed-over, sanitized version of his life, this is authentic. Things that he says make others stare. Some may even generate discomfort from viewers themselves.
Balancing Humor, Stigma and Empathy
Because, with every negative reaction to John’s behavior, there is a sense of stigma. People are often more reactive than proactive, which is all a part of the problem. This movie aims to educate viewers about the reality of the disability over anything else.
“I Swear” goes through a natural progression: from misunderstanding to social outcast to acceptance to advocate. No matter what stage the film lies in, it’s equally entertaining — not to mention empowering. Through the lens of Tourette’s, it tells a story that is individual yet universal. Most viewers of “I Swear” don’t suffer from John’s condition, but his journey remains just as powerful.
However, some pacing issues do arise. While John’s journey with Tourette syndrome is well-documented, his rise to becoming a key advocate isn’t. Rather than putting equal focus on this aspect of his life, the film only dedicates a few scenes to it.
While deeply profound, “I Swear” is also incredibly funny. Many of the things that John says are darkly comedic: shouting “I have drugs!” to the police or “You’re gonna die of cancer. Haha!” when first meeting Dottie. These moments aren’t meant to poke fun at him, however. Instead, the audience is encouraged to laugh with him.
This approach helps to bridge the gap with a misunderstood condition.
Performances That Elevate Everything
These tonal clashes never feel jarring — they’re simply a part of John’s identity. In fact, throughout the 120-minute runtime, viewers will likely find themselves growing more empathetic.
Robert Aramayo (John Davidson) delivers a masterful performance in the lead role. He commits both physically and verbally, with a portrayal that is central to the film’s success. With every line delivered, you can feel the exhaustion and emotion behind his words. He manages to balance both the quiet and loud moments well, creating an authentic persona in the process.
Don’t forget about Scott Ellis Watson, who plays the younger version of the character. As John’s tics develop, Watson is required to convey the uncertainty and fear that he feels. While he is only present for the first act, he provides the film with a strong start that smoothly transitions into Aramayo’s work.
The talented performances don’t stop there, however. Maxine Peake (Dottie), Peter Mullan (Tommy) and Shirley Henderson (Heather Davidson) round out the supporting cast.
It’s these supporting roles that take “I Swear” from great to phenomenal status. Writer-director Kirk Jones anchors the story in the power of connection. The characters of Dottie, Tommy and Heather are all integral to John’s journey — in their own unique ways. Continually putting emphasis on these relationships allows the core themes to resonate even further.
Following the 2026 BAFTA ceremony, “I Swear” only became more important. Many were quick to throw labels at Davidson after he shouted racial slurs and other offensive language. Few actually took a step back and analyzed the situation. The movie speaks for itself, allowing the audience to choose between compassion or hatred in the process.
“I Swear” will stand the test of time. Not only due to the performances, but because of its commitment to compassion. Get ready to laugh, cry and… grow in the process.
