LOS ANGELES (AP) – No sweat for the monsters against “The Heat.” “Monsters University” stays number-one for a second weekend. It brings in another $46 million, for a total of more than 170 mil after just 10 days. But Sandra Bullock and Melissa McCarthy are bringing “The Heat.” Their female buddy-cop movie opens at number-two this weekend. The movie’s $40 million opening weekend is twice what many Hollywood insiders expected. “World War Z” is third, followed by “White House Down.”
