Our guest is Barry Jenkins, the director and showrunner for "The Underground Railroad," which is based on Colson Whitehead’s Pulitzer Prize-winning novel of the same name. Jenkins talks about his artistic vision for the show, why he chose a television format over film, and what he learned from making "Moonlight" and "If Beale Street Could Talk."
