Salt
This starred Angelina Jolie, Liev Schreiber, and Chiwetel Ejiofor. Andre Braugher has a brief cameo.

Originally this was to star Tom Cruise in the lead role but he declined and the movie was rewritten for Jolie. If there's one actress who can make you believe that she has the capacity to fight men and occasionally win it's the statuesqe Jolie. I think Jolie is much better suited for this than Cruise would have been. I have trouble believing Cruise could win a fight with the paperboy.

Jolie is a deep cover CIA agent (Evelyn Salt) who is interrogating a Russian defector who suddenly states that Jolie is actually a deep cover Russian mole planning an assassination. Jolie refuses to be interrogated in turn and escapes. Mayhem ensues. Schreiber is Jolie's CIA supervisor, who doesn't want to believe she's gone bad. Ejiofor is a counterintelligence officer who does everything by the book even as he starts to notice some anomalies.

The movie is fun but mindless. The director realizes this and attempts to make up for it by plenty of closeups of Jolies' lush lips or pencil skirted legs. Jolie's character even uses her panties to escape lockdown. While this is... interesting clap lol I'm not sure it really balances out a script that has some very obvious holes in logic and some misdirection that doesn't quite work. I probably should have waited for DVD. In its defense though the movie is anything but ponderous and moves pretty quickly. It's just under 90 minutes. In general though I couldn't really care about any of the characters. They didn't quite come across as real.

"When the snows fall and the white winds blow, the lone wolf dies but the pack survives."
Winter is Coming

Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
