"Sometimes you don’t have the opportunity to discuss [those topics] your sons," says the actress, who portrays Maria Callas in the Netflix film

Netflix film Maria, directed by Pablo Larraín from a Steven Knight screenplay, sees Jolie playing the American-Greek soprano in her final days in Paris, as the diva reckons with her identity and life after a glamorous and tumultuous life in the public eye. In real life, Callas died of a heart attack at her Paris home in 1977 at age 53.

Finding the breath of Maria Callas was enough to bring things out of Jolie that she didn’t even know were in her.
