Horror films have been terrifying moviegoers for over a century now. Nothing is quite as eerie as watching something spooky in a dark theater — whether it’s demon-possessed children or sinister creatures from beyond. However, some horror movies were just as (if not more) terrifying offscreen as they were onscreen.

Sometimes, a film set — or even the cast — seems “cursed.” From unexplained natural events such as fires and strange gusts of wind to tragic occurrences such as unexpected deaths and fatal accidents, making a horror movie is not to be taken lightly. Without further ado, here are 11 classic horror movies that had strangely sinister events occur during or after production…
