‘I Swear’ Review: Down-to-Earth Tourette Syndrome Drama Is a Fine Showcase for ‘Rings of Power’ Star Robert Aramayo

Based on the real life of Tourette Syndrome campaigner John Davidson, who takes an exec credit here, “I Swear” is a biopic about a man who came of age in 1980s Scotland at a time when Tourette Syndrome was misunderstood and barely acknowledged, leading him to experience everything from difficulties dating to horrific physical violence.

The “I” in “I Swear” is played by “The Rings of Power” star Robert Aramayo, while the second part of the title is a play on the involuntary expletives prompted by his character’s condition, as well as an oath he has trouble with in a key courtroom scene. Written and directed by Kirk Jones (“Waking Ned Devine”), the film wrestles enthusiastically and mostly successfully with the potential pitfalls of making a funny yet respectful project about a condition that sometimes lends itself to laughter, even as it wreaks havoc with Davidson’s life in serious ways.
