It's Halloween and time to sit back and watch some scary movies.

We've all seen the lists compiled by various sources on just what they consider to be the scariest movies, but this time they let science determine the movies that frighten us the most.

Broadband Choices recently released their "Science of Scare" study. They started this research by putting together a list of 30 "must see" horror movies based on things like Reddit recommendation, picks from critics, and last year's "Science of Scare" list.

Next they gathered 250 people -- or "victims" -- to watch a total of 40 films. While viewing these movies, the viewers were hooked up to heart rate monitors. This would show how the movies affected the heart rate of the person watching the movie.

Are you ready for the Top 5 Scariest Movies? Here is that list...
