Horror film posters typically feature only one character's face that is supernatural or partly obscured, taking up most of the poster space against a black background. When faces are included in horror posters, there is usually only one character portrayed rather than multiple characters.

characters faces there are some that do. When faces are
included they only ever tend to have one character in the
poster or tend only to have the face of one character. The
characters face tends to be supernatural in some way or is
partly covered with black edges. In these cases the picture
tends to take up all or most of the poster and any background
tends to be black.
