I have no reason to believe there was any behind the book-the-book payoffs or endorsed deals promoting the higher use of the tobacco products in the first film over the 2nd. I would recommend, though, taking the years they had been released into account. withinWithin the last 15 years alone anti smoking-smoking awareness has increased dramatically and would effect the Ratingrating of the 2nd movie much more then the rating of when the first movie was released and viewed. I believe this is why there is such a dramatic difference that you are seeing regarding the use of the tobacco products. ---- PS first anything on the sight so be easy and Tips are appreciated! ^_^
