weekend box office transformersJAKE COYLE, AP Film Writer

NEW YORK (AP) - "Transformers: Age of Extinction" beat out Melissa McCarthy's "Tammy" on a weak July 4th weekend at the box office.

According to studio estimates Sunday, the fourth "Transformers" film made $36.4 million in its second week of release. It's a steep drop for the Paramount Pictures sequel, which had the year's biggest debut last weekend with $100 million.

The New Line comedy "Tammy," released by Warner Bros., took in $21.2 million in its opening weekend, well below expectations. The Midwest road trip romp opened on Wednesday, and had a $32.9 million gross over its first five days.

Sony Screen Gem's horror flick "Deliver Us From Evil" came in third with $9.5 million in its debut.
