Angelina Jolie has said she could consider a career in politics, describing herself as "open" to a life of diplomacy or public service.
Jolie, who last month was made an honorary dame by Queen Elizabeth for her campaigning work against sexual violence, has often been asked if she would consider stepping into politics.
But in an interview for the December issue of Vanity Fair magazine, which goes on sale next Tuesday, she said that for the first time she was warming to the idea.
"When you work as a humanitarian, you are conscious that politics have to be considered," she said.
"Because if you really want to make an extreme change, you have a responsibility.
"But I honestly don't know in what role I would be more useful - I am conscious of what I do for a living, and that could make it less possible."
When asked if she sees herself pursuing a life in politics, diplomacy or public service, Jolie replied: "I am open."
The 39-year-old actress is currently in Malta filming By The Sea with husband Brad Pitt - their first film together since Mr and Mrs Smith in 2005.
She has a long history of dedication to political and humanitarian causes, having lobbied the UN to make her a Goodwill Ambassador in 2001, and since then has travelled the world promoting a variety of causes.
In 2005, to coincide with a UN summit on meeting the millennium development goals, she made a documentary for MTV about Kenya entitled The Diary of Angelina Jolie and Dr Jeffrey Sachs in Africa.
"Africa is beautiful, marvellous, smart people, strong people, strong country and has a potential to be so much," she said at the time. "I'd love to see Africa flourish. It's magnificent and it has so much hope, so much possibility."
In 2007 she made headlines when she wrote an op-ed piece for The Washington Post calling global attention to the genocide in Darfur. She has also championed projects in Afghanistan, Haiti and Cambodia.
And she has been open in her admiration of and working relationship with William Hague, Britain's former foreign secretary.
The pair have been campaigning together since he saw Jolie's film In the Land of Blood and Honey, which depicted camps during the Bosnian war when thousands of women were raped.
Jolie, who is also the special envoy of the UN High Commissioner for Refugees, said she and "William" are "now very focused on the next stage of our campaign", despite him leaving the Foreign Office earlier this year.
She added: "We are both absolutely committed to this cause and to our partnership on this issue."
