"Cyrano de Bergerac" (1900) starring Benoit-Constant Coquelin was the only film record ever made of the original star of Rostand's famous play performing a scene from his most famous role. It is accompanied by a sound-on-cylinder recording of Coquelin's voice reciting one of Cyrano's speeches. This film is generally believed to be the first ever film produced with both color and sound. It was filmed using the nitrate film stock which has a chemical composition similar to guncotton, and is highly vulnerable to fire and decay. This film was made in the period that is often referred to as the "inflammable years of cinema".
