It was the most successful classical concert: 30 years ago, Luciano Pavarotti, Placido Domingo and José Carreras performed together with Zubin Mehta for the first time as „3 Tenors“ in the thermal baths of Caracalla on the occasion of the Football World Cup in Italy. 1.6 billion spectators watched the concert worldwide – and it catapulted classical music into a completely new dimension. Just in time for the 30th anniversary, the film „Three Tenors – From Caracalla to the World“ shows the emotional highlights of the first concert and the sequel in Los Angeles. Previously unpublished backstage material shows the tenors unadorned and offers a fascinating insight into what takes place beyond the spotlight. The film takes a completely new look at the concert legend. For the first time, Placido Domingo, José Carreras, conductor Zubin Mehta and Luciano Pavarotti‘s widow Nicoletta Mantovani talk about José Carreras‘ struggles with leukemia, their rivalries and friendships, their spectacular contract poker and life as an opera star.
