''The Centaurs is an animated film produced and directed by Winsor McCay between 1918 and 1921. There is no record that the film was completed or publicly screened. The film was destroyed by negligent storage that allowed the sole surviving nitrate film print to deteriorate into dust. All that remains are isolated fragments that total approximately 90 seconds.''
