Grand Prix is one of those racing extravaganzas that's really about racing. Although the stars are heavy-weights, they add to rather than detract from the racing yarn - Garner does wonderfully, as do Eva Marie Saint, Yves Montand and Toshirô Mifune. This is an A+ movie all the way, historically close to the fact, and well worth seeing three-plus decades later. The story line is less clichéd than most pf the racing genre - triumph, overconfidence, loss, disappointment, catastrophe, victory! And the actors aren't just pretty doodads stuck in and around racing cars, they actually seem to know something about what they're doing.
The video depicts the last of the classic era (or the first years of the rear-engine era, as you wish) of Formula One. Many of the real drivers of the 1960s had cameos in the movie, and if you watch for them you'll see one or two in almost every track scene. This is a must for those building a racing video library. Far better than "Days of Thunder" with respect to being true to the actual sport (cars with smashed in body-work haven't won Daytona in years - except with Tom Cruise driving), and widely acclaimed in its day for pure cinematic accomplishment. It's still a great, great movie (and if you've got a copy of Grand Prix Legends installed on your PC, you can go out and race the same tracks you just watched on the video).
