I can echo FB's comments on Grand Prix. At the Silverstone Classic, two years ago, the Friday night event at the main bar area was a big screen out door showing of Grand Prix and it was a brilliant evening. The movie is well worth owning on DVD for the massive amount of extras that come with it regarding 60's F1.
As FB has said, the story / plot, what little there is of it is the usual stuff, pretty thin but enjoyable. Where it scores is the stunning way it covers 60's motor racing. Each race featured in the film is actual footage from races at the 1966 season. The cars used by the actors in the film were usually run around the track driven by current F1 drivers and in some cases the actors (James Garner was apparently good enough to have been an racing driver) prior to the start of the race and then several cars in the race were re-painted in the colours of the "film cars" to ensure that the footage was as authentic as possible. I don't think you will find better footage of 60's racing anywhere so just for that, it acts as a remarkable record of its time.
Some of the F1 stars of the day also get small speaking rolls. Keep an eye out for the likes of Jack Brabham and Graham Hill joining in on the fun.
