“'Prequels' are sequels that relate the story that preceded the original film.”
“1984, Pauline Kael, The New Yorker Set in 1935, Indiana Jones and the Temple of Doom probably has to be called a pre-sequel, or prequel, to Raiders of the Lost Ark, which was set in 1936, but it isn’t pulpy in the way that Raiders was.”
