If you are a Formula One aficionado and have not seen this terrific Michael Fassbender narrated documentary — “1: Life On the Limit” — about the perilous formative years of F1, when three or four drivers died every season, you should. Set in the golden era of Grand Prix racing, “1” tells the story of a generation of charismatic drivers who raced on the edge, risking their lives during Formula 1’s deadliest period, and the men who stood up and changed the sport forever.
