Check out Angelina Jolie in first 'Salt' pics

Columbia Pictures' spy thriller "Salt" heads into principal photography this week, and Sony has released a first look at Angelina Jolie in the title role.

In the film directed by Philip Noyce, Jolie stars as Evelyn Salt, a CIA officer who is accused by a defector of being a Russian sleeper spy. Trying to clear her name, Salt embarks on a perilous mission to prove she's loyal to her country.

Also starring are Liev Schreiber, who plays Salt's boss. Chiwetel Ejiofor plays a CIA counter-intelligence officer. Kurt Wimmer wrote the original script, with Brian Helgeland having done a rewrite.

ComingSoon has provided the nice shot you can see below. You can check a second one in full size right here.

Tom Cruise was originally attached to star in the film, but when he dropped out and Jolie joined the project, the lead role had to be rewritten for her.
