First, he was portrayed by Alec Baldwin. Then Harrison Ford took the reigns for a few rides. Ben Affleck had an unforgettable turn as him, and now Chris Pine (of "Star Trek" film reboot fame) is taking on the CIA uniform of Jack Ryan. This prequel follows young Jack, framed by a Moscow billionaire for a terrorist plot, as he fights to clear his name, stop the act of terror and save his kidnapped wife (played by Keira Knightly). All in a day's work.
