Sometimes our guests have so much good stuff to say that we can’t fit it all into one show. So this week, we’re bringing you some leftovers from this summer’s interviews: Gina Prince-Bythewood, director of Netflix’s summer smash “The Old Guard;” Prentice Penny, showrunner of HBO’s “Insecure;” and Peter Medak, who talks about his documentary, “The Ghost of Peter Sellers.”
