Global box-office receipts are up slightly from a record-setting 2015. Yet Hollywood is having one of its glummest summers in a long time.

So far, this year has included roughly the same number of hits as 2015, but many more flops and moderate disappointments. Some movies that fell short of studios’ big expectations are “The Huntsman: Winter’s War,” “Teenage Mutant Ninja Turtles: Out of the Shadows,” “Independence Day: Resurgence,” “The Legend of Tarzan” and “Ghostbusters.”

Most of these movies cost more than $100 million and some close to $200 million. There have been 15 big-budget disappointments or flops so far in 2016, compared with eight at the same point in 2015.

“There are only so many available dollars in the marketplace,” said Kevin Goetz, president of consulting firm Screen Engine. “These big movies can’t all work at the level that the studios need them to in order to justify their tremendous budgets.”

Searching for the next blockbuster hit that could stand out in a saturated, winner-take all media landscape, studios have packed this year’s release calendar with sequels, reboots and superhero adaptations. Most have fallen short of their backers’ big ambitions. That could result in write-downs and losses for major studios, but also bigger profits for those that produce the few breakthrough successes.
