Moviehole.net is reporting that Ryan Gosling is set to take the helm as Jack Ryan. The report states that Harrison Ford has chosen not to reprise his role and that the next movie will be fixed on a more "young" Jack Ryan.
Philip Noyce himself tells us that neither he or Harrison Ford are returning to the Jack Ryan series - but a new Jack Ryan movie is in the works... and it'll star Ryan Gosling! (at least that's what the filmmaker's heard). Noyce WAS attached to direct "By Any Mean's Necessary", briefly last year, but he's no longer involved.
