Avatar is certainly proving itself to be a juggernaut at the box office. The movie made $68.3 million, which is the most ever for a film in its third week (it bested the first Spider-Man film). "After 17 days, Avatar has grossed $352.1 million in the U.S. and Canada, placing it at number 15 among all movies in terms of ticket sales."

In terms of worldwide sells, the movie has already made over $1 billion.

If Avatar's trend at the box office continues, it could top Cameron's last film - Titanic - as the highest grossing movie of all-time. To show how well Avatar is doing, Titanic only made $241 million during its first 17 days.
