Angelina Jolie, one of the most recognisable women in the world, is going undercover.

The Wanted star has started filming for her new movie Salt, a spy thriller in which she adopts several disguises as CIA agent Evelyn A. Salt.

In these shots, the mum-of-six models two wigs - one raven-haired and the other a blonde.

In the film Angelina tries to clear her name after she is accused - falsely or not - of being a Russian sleeper agent.

The central mystery of the movie is the true identity of the real Evelyn Salt.

Angelina - who replaced Tom Cruise in the role after he dropped out - stars alongside Liev Schreiber who plays Winter, her ally and supervisor in the CIA's Russia office, and Chiwetel Ejiofor as Peabody, a counter-intelligence officer who tries to take her down.
