I Swear – Watch the trailer for the new film about Tourette’s Syndrome campaigner, John Davidson

STUDIOCANAL have released an exclusive look at the first trailer and poster for I SWEAR, based on the remarkable true-life story of Tourette’s Syndrome campaigner, John Davidson.

Written and directed by BAFTA-nominated filmmaker Kirk Jones (Waking Ned, Nanny McPhee), I SWEAR stars Robert Aramayo (The Rings of Power, The King’s Man, Behind Her Eyes) as John Davidson. Supporting cast includes three-time BAFTA nominee Maxine Peake (Words of War, The Theory of Everything, Say Nothing), BAFTA-winner Shirley Henderson (Bridget Jones: Mad About the Boy, Trainspotting), and Cannes Best Actor Award winner & Golden Lion winner Peter Mullan (War Horse, The Magdalene Sisters).

Diagnosed with Tourette’s at age 15, John Davidson faced and overcame many hardships from adolescence and early adulthood as a result of what was a little-known and entirely misunderstood condition in 1980’s Britain. I SWEAR is a funny, heartfelt and moving account of John’s experiences.

The film is produced by Kirk Jones, Georgia Bayliff and Piers Tempest, for One Story High and Tempo Productions. Executive producers are John Davidson and Cindy Jones.

I SWEAR will be released by STUDIOCANAL in the UK and Ireland on 10th October 2025.
