Şeytan
Şeytan is a 1974 Turkish cult horror film based on William Friedkin’s The Exorcist (1973), directed by Metin Erksan, featuring Canan Perver as a 12-year-old girl named Gul, living a high society life with her mother in Istanbul, who becomes possessed by the Devil himself after experimenting with a Ouija Board. The film, which went on nationwide general release across Turkey on , is commonly known as "Turkish Exorcist" because of plot and stylistic similarities copied from The Exorcist.
The film was apparently shot with a low budget, resulting in a grainy and poor image quality. Şeytan was out of print until 2007, when it was released in DVD.
