What's the scariest movie you've ever seen?  If it's not "Sinister", then you're WRONG.  Because SCIENCE just determined that it's the ACTUAL scariest movie of all time.

"Sinister" stars ETHAN HAWKE as a true crime writer who moves into a house where a family was murdered and SCARY stuff happens.  It came out in 2012.

So how was this decided?  Someone chose 50 horror movies, then had 50 people sit down and watch them all, and their heart rates were monitored the whole time.

Fifty movies isn't exactly a comprehensive overview of the horror genre, but they chose them based on their ratings on IMDB and Rotten Tomatoes.  And the list did include many of the supposedly scariest films of all time.

"Insidious" came in second.  The test subjects reacted to both of the top movies with an average heart rate of 86 beats per minute.  "Sinister" won for keeping their hearts pounding for the entire movie, while "Insidious" got the biggest jump scare.

Here are the Top 20 scariest movies, and the average heart rates they generated:

1.  (tie) "Sinister" and "Insidious", 86 beats per minute.

3.  "The Conjuring",  85 bpm.
