Domestically, the Joss Whedon action adventure added $103.2 million, which is the first time in history a film has crossed the $100 million mark its second weekend.
That means in just 19 days, the $220 million-budgeted film has surpassed The Dark Knight's $1,001.9 million and has climbed to the 11th spot on the all-time worldwide list. It's also the fastest film to reach the $200 million mark domestically in three days, the fastest to reach $300 million in nine days, it has the highest Saturday ($69.5 million) and Sunday ($57 million) totals of all time, and the second-biggest single-day gross of all time ($80.8 million).
It should easily make it to 3rd in all time top grossing. Then it will have to take on Titanic and Avatar, currently at $1.8 billion and $2.8 billion.
