The target audience for horror films is teenagers and young adults aged 15-35, as they are curious about suspense and shock. While males are often considered the main audience, females actually tend to like horror films more than males due to enjoying the surprise and scare. Children under 15 and older adults over 50 are generally not part of the target audience, as the very young can be too easily scared and older individuals prefer to avoid the worry and suspicion that horror films provoke.
