You know...for these lists of raw dollars, they need to list the average price of a movie ticket at the time. I look at the list and I see "Star Wars" sitting at #12 with close to 800 megabucks. In 1977 I was outraged that the price of a movie ticket has "sky rocketed" to $3.50! And the matinee was an outrageous $1.75! (Remember minimum wage then was $2.30/hour)
Compare that to Titanic sitting at 1.83 Gigabucks. The average price for a ticket, $8.50 The average price of a Matinee, $5. Which movie grossed more "real" dollars?
And Return of the King (fantastic movie) cost on average $11 a ticket.
I'd love to see these movies ranked in terms of 1939 dollars. How would "Gone with the Wind" or "The Wizard of Oz" measure up considering the ticket price was a nickel or a dime.
I find www.boxofficemojo.com filled will all sorts of interesting movie box office info. They will put up all sorts of trivia like: http://www.boxofficemojo.com/franchises/vs-lotr.htm showing day by day of the 3 Lord of the Rings movies so you can see how they do vs each other.
