The Call of Cthulhu is a 2005 independent silent horror film adaptation of H. P. Lovecraft's short story of the same name, produced by Sean Branney and Andrew Leman and distributed by the H. P. Lovecraft Historical Society. It is the first film adaptation of the famous Lovecraft story, and uses Mythoscope, a blend of vintage and modern filming techniques intended to produce the look of a 1920s-era film. The film is the length of a featurette.
The original story had long been considered unfilmable, but the concept of making it a silent film and the enthusiasm that the creators had for their project earned it good reviews and several awards.
