One of Logan's screenwriters, Scott Frank, wrote both Get Shorty and Out of Sight, two screen adaptations of Elmore Leonard novels, and director James Mangold previously adapted another of Leonard's works, 3:10 to Yuma. Leonard's sardonic, neo-noir novels have been adapted for the movies over 20 times. Leonard knew cool. His influence is everywhere. Are you a fan of Timothy Olyphant's character in Justified? What about Quentin Tarantino's crime caper Jackie Brown? Congratulations, you're an Elmore Leonard fan.
Without Elmore Leonard's contributions to crime fiction, there would be no Get Shorty, no Out of Sight, no 3:10 to Yuma—and, in all probability, no Logan.
