A romance between two temperamental singing stars. Highlights include a lengthy selection from Faust, with Gigli making a most impressive Mephistopheles. The plot takes a melodramatic turn towards the climax, with the lives of the characters mirrored in their on-stage behavior. Director Carmine Gallone was something of an expert in the field of filmed opera, as witness his Tosca, Rigoletto and Il Trovatore.
