While Clancy is completing another Ryan novel, the studio hasn't read it and so hasn't decided if it will use the new book or come up with an original story. Paramount controls rights to the Ryan character, and gets first look at the new novel.
The intention is to generate several films Raimi would develop and direct, featuring Ryan at a younger, more formative point in his career than previously depicted. One invention the studio is considering is to set the film in the present, with the action triggered by a global threat.
Raimi previously demonstrated his love for spies by producing the short-lived homage to Sixties spy shows Spy Game for ABC in the late '90s. Variety says that Raimi would have to make his Jack Ryan movie immediately following his current project, Drag Me to Hell (a return to his horror roots) in order to meet the studio's desired 2010 release date, but that the director still hasn't rejected the possibility of doing a fourth Spider-man picture, which could throw a monkey wrench in these plans.
