Don’t go down there! Take a look – if you dare – at the scariest horror-movie basements

Local News

Are you sure you want to go down there?

Groundworks, which specializes in residential and commercial foundation repair, crawl space encapsulation, basement waterproofing, and concrete lifting, has created a list of the scariest horror-movie basements.

In many horror movies, basement scenes are a terrifying combination of what happens down there along with the buildup from the rest of the plot, Groundworks says in a news release. To identify the scariest basements, we developed a Basement Evil Score to subjectively rank what happens in each on-screen basement. Using a scale of 0 through 10, lower numbers indicate less scary scenes or a little bit of torture. Higher numbers indicate more devastation or a lot of death.

The company also looked at the Movie Scream Factor to understand the basement scene within the context of the rest of the movie. Using the IMDb score, higher-rated horror movies are more terrifying than poorly rated movies.

The ultimate combination is a scary basement during a scary movie. The horror movies that achieve this are at the top of the list, including “The Evil,” “Get Out” and “The Silence of the Lambs.”
