It was only a matter of time - 47 days, to be precise.

According to the box office tally site Boxofficemojo.com, "Avatar" is now the highest-grossing movie of all time domestically. The James Cameron film's business now stands at $601.1 million, ahead of the $600.8 million Cameron's "Titanic" did back in 1997-98.

Moreover, "Titanic" took 252 days to top out; "Avatar," which has been the biggest movie in the country since its mid-December release, is still No. 1 and shows little sign of flagging (and those nine Oscar nominations won't hurt).

 The film is already the global box office leader, having topped "Titanic's" $1.8 billion-plus last week.

Yes, there's been a lot of teeth-grinding over what this means. Yes, tickets for "Avatar" cost more than "Titanic," or "Star Wars," or "Gone With the Wind." Yes, the film is still down the list if you adjust for inflation. But credit where credit is due: "Avatar" was a monumental gamble - its budget is the kind of thing that can cripple studios - and it's paid off, both critically and commercially. James Cameron has got the golden touch.
