After a lackluster 4th of July holiday at the box office, Universal's animated comedy The Secret Life of Pets breathed new life into the sagging summer season last weekend with a whopping $104.3 million. This surprise hit will face two newcomers this Friday, Sony's Ghostbusters reboot and Broad Green Pictures' The Infiltrator, starring Bryan Cranston. If our predictions are accurate, it should be a close call at the box office, with Ghostbusters just barely beating out The Secret Life of Pets with $64 million.

Animated films don't normally suffer huge drops like many summer blockbusters, so we're predicting that Secret Life of Pets will drop 40%, which would would put its second weekend total at $62.5 million. Of course, with the top two so close together, it could very well turn out the other way around, with The Secret Life of Pets repeating atop the box office, so we'll have to wait and see. Box Office Mojo reports that Ghostbusters will debut in more than 3,700 theaters, while The Infiltrator doesn't have a theater count estimate. Both movies are faring well with critics, though, with Ghostbusters earning a 77% "Fresh" rating on Rotten Tomatoes, with The Infiltrator scoring a 69% "Fresh" rating on the site.
