You’re right, Avatar is only the 20th on the list of highest grossing film.

Glad to know, that one of my favourite movie, “The Sting”, is above Avatar.
I was going off of the list I hear quoted in the Industry.
You cannot expect Hollywood to know what these imaginary terms like ‘inflation’ or ‘adjusted’ are.
Can you?
I mean really.
edit: In summation, Avatar is the highest grossing film of all-time (The gross is unadjusted).

I thought that if you considered inflation and what not, Gone with the Wind is still the biggest money maker at box office. Might have got my facs wrong though.

1.537 billion dollars adjusted for inflation, which is roughly three times more than Avatar’s domestic gross.
Note: Valentine’s day also dethroned Avatar to 4th placce. That grossed $50 million, the highest since that crapfest Ghost Rider. 
The traditional trend is that during this period, films like Avatar dominate much of the first 3 months because it is the worst time of year to release blockbuster films. Does this mean ‘blockbuster’ films are now a year round thing?
Evidently so. My friend described it as pocahontas with more blue.
Was still good though
…or that Smurf killer movie.
Now number 14 in inflated domestic box office.
