Ms. Callas, American-born and Greek-educated, had made a series of appearances in Italianopera houses in the late 1940s that stunned audiences and critics and laid the foundation for her international celebrity.
Parts of the movie are jaunty and funny (the director gets the opera-buffa side of Italian Fascism), though Bellocchio treats Dalser with the gravest courtesy.
In 1957, he made his debut at the famed La Scala opera house in Milan, where much later in 1993 he became the first non-Italian to be awarded the Golden Baton.
