Angelina Jolie has replaced Tom Cruise in the new spy thriller 'Edwin A. Salt'.

The 'Changeling' actress will play the role of a CIA officer who is accused of being a Russian spy and dodges being captured by superiors who are convinced she is out to assassinate the president.

The film's screenwriter, Brian Helgeland, will have to make some adjustments to the script to accommodate for the fact that the main role will now be played by a female and the title will change slightly.

Quoted in The Mail, a source said: "Angelina is determined to make sweeping changes before filming starts.

"She's demanding the writers improve the dialogue before she sets foot on set."
