Laura Ingalls Wilder's semi-autobiographical "Little House on the Prairie" series, which inspired a classic 1970s TV show, is returning to screens this summer in a new adaptation of Wilder's beloved books. Correspondent Faith Salie talks with stars Alice Halsey, Skywalker Hughes, Crosby Fitzgerald and Luke Bracey; writer-showrunner Rebecca Sonnenshine; and executive producer Joy Gorman Wettels, about myth-making and pioneers in the American West.
