In one part of this documentary on the life and career of Maria Callas, she is returning to perform at the Metropolitan Opera House, in NYC, after a 7 year absence and a TV reporter is interviewing some of Callas' devoted fans who have been sleeping in line all night to be able to purchase tickets. One enthusiastic young man says that she is just magnetic on stage and has the greatest singing voice of the century. After viewing this film I would agree with him on both counts.
The doc, directed by Tom Volf, is a tribute to the complex and highly intelligent Callas, and much of the movie is told through her own words, vintage film clips, and some parts of her mesmerizing onstage performances. I'll readily admit I'm not a follower of opera but when Callas sang and acted onstage it was truly incredible with her range and charisma.
There's also, once she reached superstar status, the constant invasion of her privacy by the paparazzi (of course, decades before social media) , only heightened when she began a long relationship with the billionaire Greek shipping magnate Aristotle Onassis. Even more so when he left her to marry Jackie Kennedy, only to return to Callas before his death.
Overall, although the doc is perhaps overly long at just under 2 hours, I just found Callas' persona and life story to be quite fascinating.
