Tourette’s Syndrome is often misunderstood as merely cursing – and I Swear gives plenty of that to comedic effect. But as a study of a debilitating and socially ostracising condition it’s also loaded with compassion, serving as both a useful educational tool and a feelgood Brit film with the social conscience DNA of The Full Monty or Billy Elliot.

Following the story of Galashiels local John Davidson (Robert Aramayo) as he looks back on his life from an MBE ceremony (where he tells the Queen to F-off), the film charts his difficult journey from developing uncontrollable tics as an 80s teen (Scott Ellis Watson) in an unforgiving school, through an adolescence marked by parental disdain and dust-ups with people taking offence at his outbursts. By the time he’s a young man (now played by Rings of Power’s Aramayo), his prospects of getting a job, friends or a life look bleak. But when he meets a mental health nurse, Dottie (Maxine Peake) and the gruff caretaker of a community centre, Tommy (Peter Mullan), John gets the love and respect he needs to forge a path to becoming a leader in the Tourette’s community and a campaigner for greater understanding. Along the way he’ll suffer false arrest, assault and cruelty, as well as moments that restore a belief in humanity.

If that sounds dry, it isn’t. Though the script by writer/director Kirk Jones aims to enlighten, there’s inescapable fun to be had in tracking John’s misadventures. Aramayo is supremely charming as a cheeky chap who involuntarily shouts his innermost thoughts, spits food and punches people while also apologising profusely. The hurt in his eyes is as readable as the bravura of his posturing, and his delivery of the tics that mark his condition feels authentic. The resigned dismay on his face as he’s shouting ‘I’m a pedophile!’ or ‘spunk for milk!’ while making a cuppa (and worse) is both undeniably funny and heartbreaking.

He’s surrounded by similarly excellent performances; Peake is warmth incarnate while Shirley Henderson (as John’s cold Mum) is brilliantly brittle. Very nearly stealing the show, Mullan essays patience and no-nonsense kindness that is a delight to watch. Along the way audiences may learn something – not only about Tourette’s, but also about the resilience and magnificent power for empathy of people. In our current dark times, that feels like a gift at the cinema. It’s also got a banging soundtrack and is likely to figure in the BAFTA shortlist come February. So worth getting a F-ing ticket…
