It was a close call, but in the end "Monsters University" edged out "The Heat" at the box office this weekend, as according to Film.com, Pixar's latest animated hit topped Melissa McCarthy and Sandra Bullock's R-rated comedy by the score of $46.2 million to $40 million.

That's still an impressive debut for "The Heat," but the same cannot be said for fellow newcomer "White House Down," as Channing Tatum and Jamie Foxx's action thriller stumbled to fourth place with a disappointing $26.6 million.

Overall, though, no fewer than five films cracked the $20 million mark, as moviegoers spread the wealth around to "World War Z" and "Man of Steel" as well. For a full look at the box office top ten, head to Film.com.
