Angelina Jolie - Angelina Jolie Needed Salt Action

Angelina Jolie enjoyed starring in action film 'Salt' because it stopped her feeling "soft" after giving birth.

The actress was thrilled to get the chance to do her own stunts in the action movie - in which she plays a CIA agent trying to prove she is not a Russian spy - soon after giving birth to twins Knox and Vivienne in July 2008 because it toughened her up.

Angelina said: "It was difficult to switch to being an action hero for a minute. But it was so nice to have an excuse to get out of bed and get back in action and not feel so soft with the pregnancy and all that comes with it after."

Although the 35-year-old star was happy to throw herself into the character of on-the-run Evelyn Salt she did occasionally have times when she felt like she should be back at home.

Angelina - who filmed car chases, fight scenes and torture sequences for the movie - added: "I did have a moment where I found myself thinking, 'I am somebody's mom, I don't belong here.' I was on the freeway with somebody chasing me and two weeks before I was at home feeding the babies. I felt like, 'Oh, they've got the wrong person.' "

In addition to Knox and Vivienne, Angelina has four other children, Maddox, eight, Zahara, five, Pax, six, and Shiloh, four, with her partner Brad Pitt.

The screen beauty has also revealed shooting 'Salt' reminded her of the first time she met Brad, on the set of action film 'Mr. and Mrs. Smith'.

She said: "You know the great thing is he and I met during an action movie, so he's kind of like, 'Oh honey, you're bruised again from a stunt.' You know, it's sweet, it's reminiscent of the old days."
