Sony Pictures Classics has acquired Kirk Jones crowd-pleasing real-life dramedy I Swear after the films successful debut in Toronto last month.

Sony picked up rights in the U.S. and multiple international territories, including Latin America, Eastern Europe, Turkey, Southern Asia, South Korea, and Portugal, to the film from the Waking Ned Devine and Nanny McPhee director. Robert Aramayo (Game of Thrones, The Lord of the Rings: The Rings of Power) stars as Tourettes Syndrome campaigner John Davidson. Maxine Peake (Funny Cow, The Theory of Everything), Shirley Henderson (Bridget Jones: Mad About the Boy, Harry Potter franchise), and Peter Mullan (War Horse, The Magdalene Sisters) co-star. The film follows Davidson through the 1980s and 90s in Scotland. Davidsons condition, which leads him to make foul-mouthed outbursts,was barely understood at the time and was the source of misunderstandings, bullying, and harassment. But he became a passionate advocate for his community, educating Britain about the condition, which can affect up to 1 in 100 people. The film opens with Davidson receiving an honor from Queen Elizabeth. Though he cant stop himself from shouting: Fuck the Queen! just before the ceremony. The production collaborated with members of the Tourettes community, casting performers who live with the disorder and partnering with a Tourettes charity. Related Video
