Edward Norton, Monica Barbaro talk playing music icons in 'A Complete Unknown'

Edward Norton and Monica Barbaro are sharing how they got into character to play music icons Pete Seeger and Joan Baez in the new film A Complete Unknown.

Though it's a biopic centering on Bob Dylan (Timothée Chalamet) in the early '60s, Norton told Good Morning America the film is "a very intensive look at that window [of time] and the collisions between [Dylan] and Pete Seeger and Joan Baez and a number of others who were at the heart of that folk music scene" in New York City.

A Complete Unknown hits theaters Dec. 25.
