I have never been a believer of measuring the greatness of a movie in terms of gross box office sales. One billion US dollars in gross box office ticket sales in 2009 has an entirely different meaning compared to a decade back. For instance, “Gone with the Wind”, a movie shown in 1939 grossed 390 million dollars. Do you know how much that’s worth in 1939? Titanic, another James Cameroon movie, grossed 1.8 billion USD a decade back when ticket prices cost 4.59 USD.
