For anyone interested in American film history, You Must Remember This is a podcast dedicated to the "secret and/or forgotten histories of Hollywood's first century." Launched in 2014, the show is written and hosted by Karina Longworth with frequent guests from the worlds of film and journalism. Each episode explores a different aspect of Hollywood history, told with the aid of dramatic reenactments and film clips. One recent series of episodes explores the rivalry between Bela Lugosi and Boris Karloff, tracing the lives of both horror movie stars. Another recent series of episodes investigates the careers of actresses Jane Fonda and the late Jean Seberg: "two white American actresses who found great success (and husbands) in France before boldly and controversially lending their celebrity to causes like civil rights and the anti-war movement." Each episode of You Must Remember This is accompanied by full show notes, which include credits, photographs, and links to all sources. Interested listeners can also subscribe on iTunes.
