The film Raiders of the Lost Ark (1981), set in 1936, introduced Dr. Henry (“Indiana”) Jones, a young professor of archaeology and history at fictional Marshall College, whose extracurricular activities include grave robbing and swashbuckling and whose one great fear is snakes. American film producer George Lucas created the character as an homage to, and a reimagination of, the action-packed matinee serials he had enjoyed as a child. Steven Spielberg directed the films, also including Indiana Jones and the Temple of Doom (1984), Indiana Jones and the Last Crusade (1989), and Indiana Jones and the Kingdom of the Crystal Skull (2008).
