Avatar is on track to become the most successful film of all time.
The 3D science fiction film about blue aliens has made an incredible £700 million since it came out, making it the second most popular movie ever.
It had already become the fastest film to make more than $1 billion (£625m) in ticket sales worldwide.
But Avatar still has some way to go before it beats Titanic, which is the most successful film ever, after it made a whopping £1.14 billion.
Avatar toppled Lord of the Rings: Return of the King, which had been in second place.

It also cost more money to make than any other film, with a final bill of around £187 million.
Director James Cameron, who also made Titanic, said he might make two more Avatar films, so just think how much money they could make!
