An Exercise in Perspective is an experimental documentary and fundraising film, which follows the story of blind runner Phil Harrison. Born fully sighted, Phil has lost eyesight from two unfortunate moments – an injury to his left eye as a teenager, compounded by a cancer diagnosis in his right eye when he turned 60. He now has less than 5% vision, only afforded to him with an artificial iris. Many people could become reserved after such bad luck — Phil has decided to run. In 2026 he will run his first ever marathon, the London Marathon, raising money for the UK sight loss charity: RNIB (Royal National Institute of Blind People). As the frontman of infamous punk band Social Security he has always been defiant and young-at-heart. The band provide the perfect soundtrack to his story. Immersive, mixed-media and a DIY project — the documentary gives a perceptual insight into Phil’s excitable, scrappy and inspirational spirit.
