Before stories of King Arthur and Robin Hood were adapted and readapted for film, television and theater, radio scriptwriters looking for material turned to Thomas Malory's Le Morte Darthur (1485) and Howard Pyle's The Merry Adventures of Robin Hood (1883). Throughout the 1930s to the mid-1950s, their legends inspired storylines for Abbott and Costello, Popeye, Let's Pretend, Escape, Gunsmoke, The Adventures of Superman and others. Many of these adaptations reflect the moral and ethical questions of the day, as characters' faced issues of gender relations, divorce, citizenship, fascism, crime and communism in a medieval setting.
