I had been trying to view this movie for about 20 years or so. It was shot at the last 4 races of the 1981 Can Am season but was not released until 1984. It was never in theaters and was released to VHS only.
While some of the comentary is very basic and the music is oh so 80's - the shot angles both in and out of the car were quite ground breaking for the day. It is quite amazing what was accomplished with the cameras they had to work with at that time.
In addition, it is great to see the competitive but friendly interaction between Garvin Brown and Paul Newman.
The full length film can be found burried on you-tube here

Some of the video has suffered in quality but the sound remains great - particularly if you are wearing head phones.
enjoy.
