THOUGH it has been released in the US more than a month ago, “The Avengers” shows no sign of slowing down its record-breaking achievements. Walt Disney Pictures confirmed that the superhero ensemble movie has reached the $600 million box office revenue domestically. With the new achievement, the Joss Whedon-directed film officially becomes one of only three movies in history ever to reach the $600 million mark. Also bagging an estimated $1.4 billion worldwide, the Marvel Comics flick stands as the third highest grossing title of all time behind James Cameron’s “Avatar” ($2.7 billion) and “Titanic” ($2.1 billion).                                               –AS
