Jack Ryan is the central character in 12 of Tom Clancy's novels about the CIA analyst. When the debut book, The Hunt for Red October, hit the silver screen in 1990, a relatively unknown actor, Alec Baldwin, starred as Ryan in what was to become the first of many adaptations from the successful literary series. But a combination of factorsa new studio head at Paramount, some bad press about Baldwin and Kim Basinger on the set of Marrying Man, and the availability of superstar Harrison Ford, led to the replacement of Baldwin in Patriot Games and Clear and Present Danger with Ford in the lead role.
