20th Century Fox’s Avatar has become a blockbuster on an epic scale…and at a very fast rate, too. According to the studio, the movie has already earned a jaw-dropping $700 million worldwide, with $250 million of that number coming from the US. Things have also continued to be good for Fox at the box office in the family department as well, with their Alvin and the Chipmunks: The Squeakuel taking in over $100 million in the states since its release last Wednesday.
