Last yearbroke records on that highly competitive holiday weekend. And it's a model DreamWorks was set to follow withand. But the unstoppable force -- big-screen superheroes -- has scared both films to later dates. Coming Soon revealswas set for an early November 2017 release date.

However, Marvel has since announced one of their sure-to-be blockbusters will open the week before, on November 3rd. DC has countered , promising an unnamed project of their own for November 17th.
