'Iron Man 3' Breaks Box-Office Records With $175.3 Million Opening Weekend.

"Iron Man 3" blew away the competition at the box office this weekend.
Tony Stark's big return to theaters brought in a massive $175.3 million in its debut.
Box office estimates had the third film in the franchise earning anywhere from $135-$170 million.
Though it didn't duplicate the success of last year's "The Avengers" which brought in an astounding record-breaking $207 million opening weekend, "Iron Man 3" now sits second on the list, beating out "Harry Potter and the Deathly Hallows Part 2."
The film has now earned $680 million worldwide, and is well on its way to becoming one of the highest-grossing films of all time. (To rival "The Avengers," it will need to earn at least $1.5 billion.)
Here are the top five grossing weekends at the box office:

Disney will announce its second quarter earnings this Tuesday.
