Diego Luno joined BUILD to talk about his role in Netflix's "Narcos: Mexico" and the new film, "If Beale Street Could Talk." "Narcos: Mexico" explores the origins of the modern drug war by going back to its roots, beginning at a time when the Mexican trafficking world was a loose and disorganized confederation of independent growers and dealers. In "If Beale Street Could Talk," a woman in Harlem desperately scrambles to prove her fiancé innocent of a crime while carrying their first child.
