Well it appears it could just happen.  The unexpected hit Avatar has topped the box office for the 3rd week in a row.  Predictions are running high that it could take over The Dark Knight's reining title of 2nd highest grossing movie ever. 

It may even surpass the Titanic for number 1.  The sci-fi thriller raked in another 68.3 million dollars this weekend bringing its total domestic gross to $352.1 million for only a 17 day release!

Only time will tell which record will be broken, but we could see Avatar take the winning crown.
