Decasia is a 2002 found footage film by Bill Morrison, featuring an original score by Michael Gordon. The film is a meditation on old, decaying silent films and is similar in spirit to Lyrical Nitrate. It begins and ends with scenes of a dervish and is bookended with old footage showing how film is processed. Some of the deterioration was enhanced with computers to create more meaningful abstract imagery in the manner of Stan Brakhage. Nothing was done to accelerate the decomposition the actual film prints, most of which were borrowed from facilities such as the Museum of Modern Art.
The film's musical soundtrack features several detuned pianos and an orchestra playing out of phase with itself, adding to the fractured and decomposing nature of the film.
Two films have been positively identified: J. Farrell MacDonald's The Last Egyptian (1914), written, produced, and based on the novel by L. Frank Baum, and William S. Hart's Truthful Tulliver (1916).
