10 More Horror Movies That Lied About Their Premise

10. The Boy Isn't Just Your Average 'Spooky Doll' Movie

If looking at the synopsis for 2016's The Boy, you're led to believe that this is very much a 'spooky doll' sort of affair.

As is detailed, this is a film where Lauren Cohen's Greta is tasked with looking after a porcelain doll named Brahms. This task is dished out by the Heelshires as they put out an ad for a live-in nanny to look after Brahms while they are on vacation, with it shown how this doll is the family's way of coping with the death of the real Brahms 20 years prior.

Despite Greta thinking this a little odd, it's a well paying gig and she simply has to adhere to a list of rules where it pertains to Brahms. Of course, when those rules aren't stuck to, all kinds of creepy things start to happen, as Greta begins to think the doll is possessed.

After all of this setup, the final act has the shocking reveal that Brahms is still alive and is an adult who lives in the walls of the Heelshires' home. With that, it becomes apparent that The Boy was never a spooky doll sort of film, and this was merely the 'in' for a wider story about the Heelshires faking their son's death in order to cover up the fact he'd brutally murdered a young girl when he was just 8 years of age.
