Quite probably the best documentary on sports car racing or motor racing in general ever made. As a still photographer in that era I can attest to the accuracy of this film. Well photographed with great attention to detail the film takes viewers into the hearts and minds of the drivers depicted. A couple will be winners, one will retire and a close friend will lose his life. A better script could not have been written by Hollywood. The film also gives you views into places you might not get to see such as the Ferrari factory of 1972, Autodelta garage, the Matra-Simca garage at Le Mans and great film of the Targa Florio. I saw this film at its premier in 1973 at Watkins Glen while shooting the 6 hour endurance race with these same cars and watched it again just recently. It still holds up as a great motor racing film.
