At the edge of Britain - and the edge of sanity, some might say - a group of motorcyclists annually risk their lives to compete in the Isle of Man TT race.
One of these maniacs, a hairy, wank-obsessed motor-racing savant named Guy Martin, is the kind of subject documentary-makers dream about.
Martin’s hilarious bon mots combine with action sequences and stunning scenery to create a gripping documentary that doubles as a subtle treatise on freedom of choice.
Not just for the petrol heads, TT3D is a life-affirming joy ride for anyone with a heartbeat.
