10 More Horror Movies Which Broke The Fourth Wall To Scare You

In 1959's House on Haunted Hill, eccentric millionair Frederick Loren (Vincent Price) invites five guests to his mansion, which is supposedly haunted. If the guests stay the whole night, Loren promises to reward them with $10,000 each.

In the end, it's revealed the house isn't haunted, and Loren concocted the whole scheme to murder his manipulative wife. (He probably didn't need to bring anyone over to do that.)

Nevertheless, one guest, Watson, is adamant there are supernatural forces among them. Just before the movie ends, Watson looks at the viewers, warning them the ghosts will "come for you".

It may be a pretty straightforward fourth wall break, but it's effective since it's the last thing viewers hear (apart from one last maniacal laugh).

But that's not all. House on Haunted Hill was directed by William Castle, who's known for concocting elaborate gimmicks for his movies. In fact, our previous such list included another William Castle classic, The Tingler.

So, it's no surprise Castle devised another way for the film to break the fourth wall. When House on Haunted Hill was originally released in theatres, a plastic skeleton was programmed to pop up in front of the screen during a key scene, scaring the living daylights out of the audience.

It may sound like a corny idea now (and back then), but this gimmick was sure to have given plenty of people the fright of their lives.
