Kenneth Branagh may not be doing the sequel to Thor, "The Dark World," but what he is doing is the next Jack Ryan movie.
Based on the series of Tom Clancy novels, Jack Ryan stars Star Trek's Chris Pine, who follows in the footsteps of Alec Baldwin, Harrison Ford and Ben Affleck.
The movie also stars the Man of Steel's Kevin Costner, as CIA Agent William Harper.
This time, in the prequel, Jack Ryan finds himself working for a Russian tycoon where he unravels a plot to take down the U.S. economy, gets framed for it and has to go on the run.
Jack Ryan has a December 25, 2013 release date.
