On this week's episode of "Under the Radar with Callie Crossley," we take a deep-dive into our current love of horror films, including the wildly successful remake of Stephen King's "IT" and the screamfest "Happy Death Day." We also discuss cringeworthy Halloween costumes, trans models making waves, movie remakes with all-female casts and the end of "Fashion Police." Guests: Rachel Rubin, professor of American studies at the University of Massachusetts Boston, and Michael Jeffries, associate professor of American studies at Wellesley College. In our Lagniappe segment, we get a behind-the-scenes look into the spooky world of ghost tours straight from the source: two ghost-tour guides who walk (or drive!) through the city, telling the true-crime tales of grisly murders, serial killers and hangings from the early days of Boston's founding. What does it take to be a ghost-tour guide, and what drew them to the business in the first place? Guests: Meaghan Dutton, tour guide for Haunted Boston, and Tim Carr, tour guide and assistant general manager of Ghosts and Gravestones Boston.
