10 Horror Movie Trailers That Gave Away The Entire Plot

In Dream House, Will Atenton moves into his new home with his wife and two daughters. Everything seems hunky-dory at first but Will soon discovers that a man called Peter Ward supposedly murdered his family in his house five years earlier. Because Ward was recently released from a mental hospital, Will becomes worried that he may return to the house to kill again.

When Atenton visits the institution that Ward stayed at, he discovers a horrifying truth - He IS Peter Ward. Worse still, the "family" he has been living with is nothing more than a well-constructed delusion that he conjured in his mind.

Sadly, many people who saw the film weren't shocked at all by this revelation since the trailer told us all about it. Even though the premise alone was intriguing enough to fill a trailer, the two-and-a-half minute long teaser spent a good 75 seconds repeatedly telling the viewers about Will's true identity.

The trailer doesn't spoil every twist but a lot of potential viewers were turned off by it, believing the entire film had been ruined for them.
