Movie scenes where the actors were actually terrified

Horror films are supposed to scare us—heck, it's right there in the name of the genre, after all. The whole reason we line up to watch horror movies is to experience the safe thrill of being rattled, startled, and occasionally even downright terrified by fictional objects on a screen. It's all totally fake, of course—that's a big part of the fun—but that feeling of fright is very real. In fact, even from the comfort of a well-lit set making it perfectly clear that what's going on is just being orchestrated for the entertainment of millions, there have been times when horror movie scares have even managed to frighten the actors and actresses bringing them to life. Let's pay tribute to these brave souls by taking a fond look back at some of the times directors engineered scenes that actually scared the crap out of their performers for the sake of cinema.
