Would not include DVD/VHS/Blue-ray sales as that is not box office.
I don't know if Gone With the Wind will ever be taken down on these inflation adjusted lists. I guess Titanic and Avatar came pretty close, so it's possible. But Endgame is killing it but still way behind. Having said that, I would think this would be incredibly hard to calculate for Worldwide like they are doing here.
Boxofficemojo has only domestic totals adjusted for inflation.
