The biggest problem with "Pushing the Limits: The Making of 'Grand Prix'" was that although IMDb lists it as a 42 minute film, it is only 29 minutes. And, considering that "Grand Prix" was a nearly three hour film, 29 minutes just isn't enough--especially since this was such a highly unusual shoot and because the film was so technically demanding. There just isn't enough background information to make it a must-see.
This is NOT to say it's not worth watching. The film was interesting in many ways. First, learning how difficult how it was to get the cooperation of the racing teams was interesting--they apparently were NOT thrilled with the idea of making the movie. Second, although many praised John Frankenheimer's skills, no one seemed to like him and he was described as a very abrasive guy. Third, and most importantly, you get to see James Garner go nuts--screaming at a stupid local guy who was holding up the film shoot! This was pretty funny and was the sort of background stuff I like! Worth seeing, as it's included on the disc for "Grand Prix"--so it's not like you need to search high and low for this little film.
