This a beautiful, exciting, riveting examination of Grand Prix racing, as told through the observations and intertwining personal lives of four professional Formula 1 drivers and their respective love interests. The romantic and philosophical interludes are mere reprieves from the exciting, heretofore unseen, technically majestic racing action camera work. Bear in mind, miniature cameras were not available in the sixties, and the engineering know-how and chutzpah required to strap a large analog camera to the front of a race car going 180 mph is truly awesome. Yves Montand is the most interesting character, with a complex triangular relationship between his wife, the lovely Eva Marie Saint, who is a welcome distraction from his troubled marriage, and his obsession with racing. Garner is fascinating as the vexed, displaced professional racer looking for a new drive, and finding a successful assignment with Toshiro Mifune's nascent racing company (the theatrical equivalent of Soichiro Honda's formidable Honda Motors). Brian Bedford is convincing as a world class racer recovering from a deadly crash, and simultaneously picking up the pieces of his broken relationship with his disapproving spouse, the captivating Jessica Walters. Antonio Sabàto is believable and likable as a young, world champion motorcycle racer who has made the transition to Formula 1, although his ongoing squabbling with his beautiful girlfriend, Françoise Hardy, who we never really get to know, although we would like to, is an unnecessary distraction at best. As the movie progresses he continually receives better dialog and has a touching and tragic scene at the end, as he rolls into the Ferrari pits in utter and complete disbelief and despair. Many famous Formula 1 drivers of the day appear in the film including Jim Clark, Jack Brabham and many others, which lends an air of "You are There" realism. Many of them, such as Graham Hill, are not mere cameos, and actually participate in many dramatic scenes. The cars are the stars in this petrol head blockbuster, although you will find the attractive and talented supporting cast and subplots an interesting distraction. Many characters appear one-dimensional, although this may be due to heavy editing to reduce the film to a tolerable running time. One of the top film from the sixties, and Frankenheimer at his finest.
