Actress Angelina Jolie has admitted that she was more protective of her children with partner Brad Pitt - Maddox, 10, Pax, 8, Zahara, 7, Shiloh, 5, and twins Knox and Vivienne, 3 - after filming some of the brutal scenes for her directorial debut In the Land of Blood and Honey which dealt with brutality against women during the Bosnian conflict.

They liked to visit the set and play in the fake snow, but there were many days when they couldn't come because we were filming scenes that weren't appropriate for children, explains a concern mother to the Daily Telegraph.

But whenever I called cut and we had a break, the kids would come and play soccer with the cast and we'd all laugh because they brought levity and love to something that was so dark. I was always so happy to see them I probably smothered them with love because of the subject matter I was dealing with, she added.

The United Nations Goodwill Ambassador also admitted sometimes she could not sleep at night and burst out crying thinking about the people who suffers over the world.

If I wasn't able to somehow bring attention to issues when I go to other countries, it would weigh on me heavily, explained the Beyond Borders actress.

Take a look at the roles the actress has in her real life.
