Carnival of Souls: Creating Horror On A Low Budget

Source: (IMDb).

In 1961, Herk Harvey was working for Centron, an industrial and educational film company. He was driving home to Lawrence, Kansas, when he stopped to explore the Saltair Pavilion outside Salt Lake City, Utah. The pavilion, which was an abandoned ballroom, inspired Harvey. Later, he called his friend John Clifford, to ask him to write a screenplay based on the pavilion. The only restriction was the final scene, which would feature the ghouls dancing in the ballroom. Within three weeks, Clifford had written Carnival of Souls, the story of Mary Henry (Candace Hilligoss), a survivor of a car accident after a drag race.
