Mannequins were a frequent motif in the works many early 20th-century artists, notably the Metaphysical painters Giorgio de Chirico, Alberto Savinio, and Carlo Carrà. Shop windows displaying mannequins were a frequent photographic subject for Eugene Atget. Mannequins are a common theme in horror fiction. Many people find mannequins disturbing (due in part perhaps to the uncanny valley effect), especially when not fully assembled. Abandoned nuclear test sites consisting of entire towns populated by mannequins appear in such films as Kalifornia, Mulholland Falls, and the 2006 remake of The Hills Have Eyes.
