The film “I Swear,” by writer/director Kirk Jones, follows Scottish activist John Davidson’s life with Tourette’s Syndrome from childhood to adulthood. I had heard of this neurological condition in my past work, but only fully understood its effects after watching the film. For those unfamiliar with the effects or how they appear in public, individuals with the condition can be easily misunderstood. Some may be surprised or offended, which can even lead to police involvement.
The filmmaker’s screenplay, based on the real-life story of Davidson, appears to be authentic and informs the audience about the condition. Davidson is portrayed by BAFTA Best Actor awardee Robert Aramayo (“Game of Thrones”). It is an outstanding performance as Aramayo effectively acts as if he has the neurological condition with tics, involuntary jerking, and uncontrollable shouting of offensive language. While this condition is nothing to laugh about, the script is not dull or dry, and Aramayo’s performance can be seen as quite amusing in a couple of scenes.
The story traces his life from playing sports at 14 to facing misunderstanding and later, run-ins with the law as he becomes an adult. At times difficult to watch, it clearly depicts how Tourette’s Syndrome was handled in the past and its eventual medical recognition. The film remains compelling and engaging without taking a documentary approach.
The film is deeply moving, depicting Davidson’s heartbreaking early experiences and his growth into a public educator about Tourette’s Syndrome. Despite the difficult scenes, this is a valuable and educational film. Davidson has been formally recognized by Queen Elizabeth II for his advocacy.
Cast: Davidson, at age 14, is played by Scott Ellis Watson, an excellent actor. His mother, Heather, is played by Shirley Henderson. A nurse knowledgeable of the condition, Dottie (Maxine Peake), helped change the course of his life. John’s boss in a new job is Tommy (played by Peter Mullan). All supporting actors are effective in their characters.
The film is now playing in theaters as of April 24, 2026.
