‘I Swear’ Review – Heart Sans Sap, Cursing Aplenty [Milwaukee Film Festival 2026]

The sixth outing in the director’s chair for filmmaker Kirk Jones, I Swear dramatizes the real-life story of touretter John Davidson (played by Robert Aramayo). Tourette’s Syndrome, for those unfamiliar with the condition, is a nervous system disorder that causes various tics, the most prolific being erratic and explicit language. However, as I Swear expertly showcases, the syndrome is far more than ill-timed outbursts of curse words. Davidson’s story is one of societal frustration, finding your people (both with and without the condition), and using your voice to help others rise. The subject and subject matter are handled with absolute care and understanding under Kirk’s measured vision and Robert Aramayo’s BAFTA-winning performance.

The film kicks off with the greatest exclamation to democracy ever uttered (*%#! the Queen!), as a nervous John Davidson prepares himself before entering an awards ceremony hosted by Britain’s royal family. Right away, the film tells us what it is: a triumph over adversity that blends humor and human drama with education. It’s an important setup, as the film flashes back to Davidson’s 1980s youth, where we see his time as a star soccer recruit flatline as his condition takes hold. Davidson’s life spirals from there. Some aspects, like school bullying and accidental run-ins with authority figures, are expected but important to empathizing with young Davidson’s (young version, played with heart by Scott Ellis Watson) new everyday life. The more tragic, a complete meltdown of his family system, is unsettling if quick. His father (Steven Cree) is never given enough screen time to explore his alcohol coping tendencies. However, his mother Heather’s descent into easy fixes and blaming is crushing and convincing. Harry Potter series actress Shirley Henderson (Moaning Myrtle) gives a layered performance as Heather. Someone who loves her son, but also feels cursed by him as the entire family exits the picture. It’s bitter, she’s tired, and fills each conversation with ‘only medication and your mother can save you’ energy.

From there, the viewer and Davidson find refuge in a host of characters. Maxine Peake plays Dottie, the mother of a childhood friend and a retired mental health nurse. Screen vet Peter Mullan plays maintenance man Tommy Trotter. Together, they help Davidson build a life and an understanding of himself that carries the film forward into its second half. After that, the film is primarily a 3-actor show as director Kirk fills the screen with these tour-de-force performances. Peake and Mullan are great vessels to get the film’s main message across: patience, love, and a shared responsibility between the diagnosed and those who understand their struggle can help change the path for people quickly left behind by a normative world. Together, they are the soul of the movie, with the filmmakers clearly hoping the audience will follow their lead after they exit the theater (in my case, the beautiful Oriental Theater for the Milwaukee Film Festival). Both performances are perfectly warm and reflective and shouldn’t be left out in discussions of I Swear.

I say this because the movie is anchored by The Rings of Power actor Robert Aramayo, who leaves Elrond’s elf ears behind to bring an acute naturalism to his performance of main character John Davidson. Aramayo’s physicality and timing of the fitful Tourettes Syndrome never feel out of place or overplayed. In fact, the movie as a whole does an amazing job of never veering into sentimentality. While many moviegoers left with tissues dabbing their eyes, the filmmaking never felt like it was forcing that reaction out of audiences. It straddles the line between feel-good and reality with every story beat and lands squarely on the side of letting the real inform our feelings. Anyone with an ounce of empathy will grasp the film’s message and hopefully take it with them into life. 

I Swear continues at the Milwaukee Film Festival on Tuesday, April 21st, and releases nationwide April 24th, 2026, courtesy of Sony Pictures Classics.
