I Swear ReviewJohn Davidson (Robet Aramayo) lives with Tourette syndrome, for which he is ostracised — until he meets kindly Dottie (Maxine Peake). As far as cosy, feel-good British films go, I Swear begins in irreverent form. As John Davidson (Robert Aramayo) lines up to receive his MBE from Queen Elizabeth II, his nerves get the better of him. Without ever punching down, it recognises the inherent absurdity of John’s sweariest tics — given extra oomph in a Scottish accent. It’s fair to say this is the cosiest mum-and-dad-friendly film to feature dialogue like, “Show me your knockers!” and, “I’m a paedophile!”
