Tom Clancy fans, unite! The author's seminal hero Jack Ryan returns for a new adventure, and this time he's played by Chris Pine. I'm curious to see if Pine's performance holds up to the other actors who have portrayed the skilled CIA analyst; Alec Baldwin, Harrison Ford, and Ben Affleck have all taken on the role. Will Pine do Jack justice? And how will Keira Knightley fare as his wife? We'll find out on Jan. 17.
