Writer-director Todd Field made two acclaimed films in the early 2000s and then disappeared from the big screen for 16 years. “Tár,” about the scandalous downfall of a classical music conductor, marks his return. The movie burst forth in dramatic fashion: Its screenplay took him only three months to write.In this episode of “The Envelope,” Field breaks down how a Górecki composition inspired the internal rhythm of lead character Lydia Tár and discusses what it was like collaborating with star Cate Blanchett, who “always wants to do things that are dangerous.” He also explains why he’s delighted by reactions to his film — even those that are ferociously dismissive. To read a full transcript of this interview, please visit the episode page at latimes.com.
