Heading into this weekend at the box office, it was expected to be a very close race between last weekend's winner The Secret Life of Pets and Sony Pictures' Ghostbusters reboot. As it turned out, both movies came in a bit under their weekend projections, but it still remained a close race, with The Secret Life of Pets coming out on top with $50.5 million in its second weekend in theaters. Ghostbusters wasn't too far behind, though, with a solid opening weekend of $46 million.

We were predicting that Secret Life of Pets will drop 40%, which would would put its second weekend total at $62.5 million, since most animated movies don't drop as much as other summer blockbusters. Box Office Mojo reports that The Secret Life of Pets dropped 51.5% with a healthy $11,541 per-screen average. This animated comedy has now taken in an impressive $203.1 million domestically and another $50.8 million internationally for a worldwide total of $253.9 million. The movie still hasn't opened in key international territories such as France (July 27), Germany (July 28) and China (August 2) yet.

For one bustling Manhattan apartment building, the real day starts after the folks on two legs leave for work and school. That's when the pets of every stripe, fur, and feather begin their own nine-to-five routine: hanging out with each other, trading humiliating stories about their owners or auditioning adorable looks to get better snacks. The buildings top dog, Max (voiced by Louis C.K.) a quick witted terrier rescue who's convinced he sits at the center of his owner's universe, finds his pampered life rocked when she brings home Duke (Eric Stonestreet), a sloppy, massive mess of a mongrel with zero interpersonal skills. When this reluctant canine due find themselves out on the mean streets pf New York, they have to set aside their differences and unite against a fluffy-yet cunning bunny named Snowball (Kevin Hart), who's building an army of ex-pets abandoned by their owners and out to turn the tables on humanity...all before dinner time.
