DAVOS, Jan 29: Angelina Jolie fans may have to settle for re-runs because the US actress has found humanitarian work with the UN's refugee agency more fulfilling and interesting than her erstwhile day job.

"It's harder for me to go back to work now, I've had a few months off and I'm having trouble going back to work," the award-winning star of "Girl, Interrupted" and "Tomb Raider" told media at the World Economic Forum Saturday.

"I'm finding my time at home with my son and taking him around, and travelling to UNHCR programs or other parts of the world is just more fulfilling and more interesting to me. And I know it's more important."

All the same, she added, keeping near the spotlight is crucial to continued aid for people helped by the United Nations High Commissioner for Refugees.

Angelina Jolie, who has spent four years as a goodwill ambassador for the UN agency, had carried out field missions to 20 countries, including Cambodia, Ecuador, Ivory Coast, Sierra Leone, Sri Lanka, Sudan and Thailand.

She said the first year was spent under radio silence because "I wanted to have at least a solid year to know that I really supported UNHCR, and to know what I was talking about."

The US celebrity has met business leaders here and is also discussing the fundamentals behind refugee crises, aside from the Asian tsunami which she noted was essentially a natural disaster.

"All of these other deaths are avoidable, and a lot of these situations are man-made, and we can stop them," she stressed.

Talks with corporate chiefs went well, Ms Jolie added, because "at the end of the day, businessmen have children, businessmen do care", and understand they have a responsibility.-AFP
