Director: Kenneth Branagh. Cast: Chris Pine, Kevin Costner, Kenneth Branagh, Keira Knightley. 105 min. Rated PG-13. USA/Russia. Action/Thriller.
For a Jack Ryan re-invention, they start from 9/11 - meaning they're following the James Bond route: ignore all prior movies and start fresh (even Ryan's first killing happens in a bathroom, Casino Royale-style). They don't even attempt some minimal validity to the older films, like they did in Star Trek by creating an entire time-shift of events; probably thinking Chris Pine pulled it off as Kirk on the Enterprise, so he can pull it off here as Ryan in the CIA. But neither Pine has Harrison Ford's cinematic weight, nor does the franchise have the magnitude of James Bond.
PS: Sorry, you need to have watched at least four other movies (Patriot Games, Clear and Present Danger, the 2006 Casino Royale, and the 2009 Star Trek), to understand what I just said above.
