10 Amazing Trailers That Tricked You Into Seeing Terrible Horror Movies

10. A Cure For Wellness

If you're particularly scared by mouth-horror, you probably remember the marketing for A Cure For Wellness. The trailer teased the story of a man who gets trapped in a super creepy wellness centre that's clearly up to no good, offering quick glimpses at the kinds of horrifically weird practices the "doctors" put patients through while there.

Keeping things mysterious, viewers are given quick shots of a drill going into someone's mouth, patients submerged in water and peculiar parasites in the drinking water. What does it all mean? Who knows! But it looks big, lavish, and spooky, and promised an imaginative return to the genre for director Gore Verbinski.

Of course, all of that is still true of the finished film, but only in part. At a sprawling two-and-a-half hours in length, A Cure For Wellness features just as many good ideas as it does bad, but its convoluted plot, not entirely convincing acting and wonky tone ultimately results in disappointment.

It's cool to see a director go completely nuts, but you can't help think there's a better, tighter horror film in there somewhere.
