Angelina Jolie is known for her role as UN Ambassador and for her humanitarian work but she recently revealed that she has not ruled out entering politics in the future.

The Hollywood actress explained that she is open to anything that makes a difference and helps those in need.

"Wherever I'm useful, I will go. I will do whatever I can to help people. You never know where life's going to take you," she said.

Speaking at the London premiere of her film Unbroken, which she produced and directed, she also revealed that she hasn't retired entirely from acting.

"I have a few more things I'll do as an actor, but I'd be very happy to stay behind the camera," she said.

The war drama film stars British actor Jack O'Connell as Olympic athlete Louis Zamperini, who spent years in a Japanese prisoner-of-war camp after his warplane crashed and left him stranded at sea for 47 days.

The release of this film comes during an eventful time for the actress, who got married three months ago and received an honorary damehood from the Queen in October for her campaigns against sexual violence.

"It meant a great deal to me because it was for foreign service, for PSVI (Preventing Sexual Violence Initiative), which I want to dedicate my life to," she said.

"You always hope that when you work on these issues you are making a difference, and it gave me that support to feel that we are actually making a difference."
