Supernatural film
Supernatural film is a film genre that encompasses themes related to gods, goddesses, ghosts, apparitions, spirits, miracles, and other extraordinary phenomena. These themes are often blended with other film genres, such as comedy, science fiction, fantasy, and horror. Historically, the primary goal of supernatural films was not to terrify audiences but to offer entertainment, often in whimsical or romantic contexts. The film genre is part of several hybrid genres, including supernatural comedy films, supernatural horror films, supernatural religious films, and supernatural thriller films. Early depictions: Films with benevolent ghosts 

Ghosts in cinema date back to the era of World War II, with post-war romantic comedies frequently featuring apparitions. Initially, these supernatural entities were portrayed more as entertainers rather than frighteners. Notable examples include:
