Thelma Schoonmaker is the legendary, now eight-time Oscar-nominated, three-time Oscar-winning editor of pretty much all of director Martin Scorsese’s portfolio. She’s as integral to the success of his films as the maestro himself. Their latest work together is “The Irishman,” the Netflix original film that recently racked up 10 Oscar nominations, Schoonmaker’s work among them.At three-and-a-half hours, the film is a contemporary American epic, and yet it moves like lightning. Each sequence propels the vast narrative forward. On this episode of “The Call Sheet,” Schoonmaker details the work that went into assembling the film, discusses Robert De Niro’s brilliant performance (after having observed his trajectory from the editing suite for decades) and much more. Also, in a bonus interview, sound mixer Tom Fleischman and sound editor Eugene Gearty explain how the power of the film lies in its subtlety and quiet moments.
