We had never scene "Rigoletto" and enjoyed it tremendously. I knew much of the music and now can appreciate the opera. That evening we saw "Quartet", about retired opera singers, with the Maggie Smith character having gotten 11 curtain calls for playing Rigoletto's daughter about four decades earlier. We also didn't realize that the lovely double duet in the opera was known by opera aficianados as the "quartet", and the movie connected the dots. The opera is timeless - love, passion, betrayal - which permeated "Quartet" and so many movies today.
