Judging from the preview, director Kenneth Branagh ("Thor") and screenwriters Adam Cozad and David Koepp really like the Jason Bourne movies, as "Jack Ryan" appears to have as much in common with Robert Ludlum as it does with Clancy, who died this week at age 66.
Like Bourne, the CIA operative Ryan is haunted by flashbacks and appears not to fully grasp what's happening around him.
But he slowly starts to figure out that an international terror plot is about to strike at some of the world's biggest cities, including Tokyo and London.
"It's gonna be a wipeout," Ryan says at one point.
In the tradition of spy tales, including Clancy's best (the movie is based on the novelist's characters but is not adapted from a book), people may not really be what they seem, including his wife, Cathy (Keira Knightley).
With a thick Russian accent, Branagh plays an apparent baddie named Viktor Cherevin. The cast includes Kevin Costner as a Ryan colleague.
The Paramount release is the first Clancy-based movie since 2002's "The Sum of All Fears."
