Details

Based on the inspiring, extraordinary life story of notable Tourette's Syndrome campaigner John Davidson, MBE, I Swear stars Robert Aramayo (The Lord Of The Rings: The Rings Of Power, Game Of Thrones) with a supporting cast including three-time BAFTA nominee Maxine Peake (Funny Cow, The Theory Of Everything), BAFTA winner Shirley Henderson (Bridget Jones: Mad About The Boy, Harry Potter franchise) and Cannes Best Actor Award winner and Golden Lion winner Peter Mullan (War Horse, The Magdalene Sisters).

Jones' emotionally engaging, funny and compelling script charts Davidson's Tourette's diagnosis at the age of 15 years old.

Set within 1980s Britain, the story follows him throughout his troubled teens and early adulthood, and explores this little known and entirely misunderstood condition, along with his attempts to live a 'normal' life against the odds.

The production worked closely with the Tourette's community, casting individuals who live with Tourette's, and collaborated with a Tourette's charity.

I Swear, released on DVD and Blu-ray 29th December 2025 from StudioCanal, is produced by Kirk Jones, Georgia Bayliff and Piers Tempest, for One Story High and Tempo Productions. Cindy Jones and John Davidson serve as Executive Producers.
