According to researchers at the University of Westminster, watching horror movies burns calories.  That's because getting scared causes your heart rate to increase.  You burn a third more calories than normal when you watch something scary, which is the equivalent of a candy bar.  Here are the 10 movies that burn the MOST calories:
