The Hollywood actress stars as a tough undercover agent in the upcoming action film, but she received a mixed response from her eldest four children when she showed them the movie trailer.

And although the onscreen violence didn't bother Maddox, eight, Zahara, five, and Shiloh, four, Jolie reveals her six-year-old son Pax "got upset" when he saw his mother apparently getting hurt onscreen.

Jolie says, "Half of them were uninterested. Pax got upset because someone was trying to hurt his mom... He got mad. But then I explained to him that I'm fine."

The actress also reveals her constantly-changing looks for the new movie left all of her kids baffled. She adds, "They're very confused, to be honest. I think they don't quite know what to think. Even the change of hair colour is confusing for them."
