Premise: The Ghost and Mr. Chicken is a 1966 American comedy-drama film starring Don Knotts as Luther Heggs, a newspaper typesetter who spends a night in a haunted house, which is located in the fictitious community of Rachel, Kansas. The working title was "Running Scared". The title is presumably a humorous variation of the film "The Ghost and Mrs. Muir" (1947).
Hypothesis: Rachel, Kansas does not exist as it is in The Ghost and Mr. Chicken
