Depending on your perspective, Days Of Thunder was either one of the best or worst motorracing films ever made. It was definitely exciting and featured a good story (if a bit similar to Top Gun). Then you have the actual racing and to the uninformed you would watch Days of Thunder and think NASCAR cars of the 90's were indestructible. The amount of beating and banging that went on in that movie was borderline ridiculous. That said the movie was a huge part of my early car dude development. I saw that Movie and instantly cars became more important than simply getting me to and from various sports practices.
The best part is there now a 30 min video on YouTube taking a look behind the curtain. An inside look into one of the first big production car movie of the 90's.
