Hilarious thread over at Boxofficemojo.com
Someone dug, and dug, and dug, and dug to find tangible data for Gone With The Wind's box office run.
It turns out there were some MAJOR mis-calculations. GWTW never made an adjusted $2 billion dollars in the US. It was nowhere close to that. Adjusted, it made about $400 million on its first run and about $700-800 million among all its runs.
So Avatar is going to most likely beat it for adjusted gross.

Back from the dead, I'm afraid.
