10 Movies That Used Insane Gimmicks To Get Attention

This classic horror film about a group of characters who stay overnight in a haunted house functions perfectly well without the need for any gimmicks, yet one is thrown in anyway, because why not? 

This time, certain theatres would be equipped with plastic skeletons in each screening, hung in the corner out of view. Then, during a climatic scene where a skeleton emerges from an acid vat, it would swing down over the audience's heads, once again creating the effect of the movie being so terrifying that it's actually bursting out of the screen. Of course, there needed to be a dumb, made up name for this effect, and so it was referred to as "Emergo." That does sound a lot cooler than "we're going to throw a freaking plastic skeleton at you in the middle of the film." 

Supposedly a lot of theatres stopped using the trick because kids would come in specifically to shoot the skeleton with slingshots. That's probably why this sort of thing doesn't happen anymore; they just had to ruin it for everyone. House On Haunted Hill was hugely successful at the time, and it's still a phenomenal movie that holds up all these years later. Although if you want the full experience, you'll just have to get a friend to throw a plastic skeleton at you while you're watching it.
