In connection with the East Tennessee Historical Society’s current “Lights! Camera! East Tennessee!” exhibit, we’ll join in a lunchtime chat with historian and civil-rights champion Robert Booker, about Black Knoxville’s experience with motion pictures, from the all-Black Gem Theatre, which Booker remembers vividly and fondly, to the city’s segregated Bijou Theatre, strictly segregated in ways hard to understand today, but also the only theater in town where people of all races could watch the same movie at the same time. Come to the lunchtime presentation, bring a sandwich, and then have a look at the pretty dazzling exhibit just down the hall. Free program.
