This lively, romantic, revolutionary Silent movie played on Turner Classic Movies "Silent Sunday" on January 10. 2021. I set the DVR for this movie before looking into the particulars of the movie. This is a tale of seduction, abandonment, and revolution, set in 18th century Naples. This is the only screen appearance by Russian Prima Ballerina Anna Pavlova, in the title role. (Note: "Dumb" means "Deaf/Mute.") This film has a very lively soundtrack, and set a record for costume design ($300,00 in 1915!). This movie is based on the revolutionary opera "Masaniello," the libretto of which took Brussels by storm, and led to the creation of Belgium! This anything but the "run of the mill silent movie."
