For some, Maria Callas was the literal embodiment of opera on Earth. Her truest fans are more religious than artistic. Others find her technique lacking or her personality off-putting such that they are dismissive of her achievements. Whatever you think of her talent, this documentary shows her life was as much an opera as her singing was.
The mostly untried Tom Volf is generous with footage and recordings of Callas’s singing. Full arias are presented, sampling her voice through the years. Each punctuates events covered in the supporting interviews and her own letters. The letters are provided voice by Joyce DiDonato, who often manages to sound so much like the author it is like listening to her speak. The most intriguing of the interviews, with David Frost from 1970, serves as backbone to much of film. The use of the interviews, however, presents a challenge for viewers. The movie is primarily told chronologically, but the inter-cut later information makes some of the events and their impacts in her life confusing.
However, by the end of this documentary you will be able to infer much about the woman behind the music. This is very much Maria telling you who Callas was and Callas providing a window as to who Maria was. How you parse that information and react to the personality, and her talent, is going to be up to you.
