The Las Vegas ensemble comedy “Think Like a Man Too” topped a slow weekend at the summer box office with $30 million, besting blockbuster holdovers from last week and Clint Eastwood’s new Four Seasons musical “Jersey Boys.”

The Kevin Hart sequel “Think Like a Man Too” narrowly edged out “22 Jump Street,” which earned $29 million in its second week of release, according to studio estimates Sunday. The DreamWorks animated film “How to Train Your Dragon 2” slid to third with $25.3 million.

The top three films are all sequels that moved into the big box-office summer season following surprise hit originals released in the springtime.

Moving into summer’s bigger competition actually diminished Sony Screen Gems’ “Think Like a Man Too.” The first film, also directed by Tim Story and starring mostly the same ensemble led by Hart, opened with $33.6 million in April 2012.

Warner Bros.’ “Jersey Boys,” Eastwood’s adaptation of the Tony-winning Broadway musical about Frankie Valli’s group, opened in fourth with $13.5 million. The film drew an overwhelmingly older audience, with 71 percent of its moviegoers over the age of 50
