Angelina Jolie's acting career is to take a ''back seat''.

The 'Maleficent' actress wants to focus more of her time on writing and directing, as well as on her work with the United Nations (UN), for who she is a special envoy of the UN High Commissioner for Refugees, so only plans to make ''a few more'' movies.

She said: ''Acting is going to take more of a back seat. I've had a wonderful career and I'm very happy to have had all the opportunities to tell stories and work for as long as I have.

''I'm sure there'll be a few more films but I'm happy that I'm able to be selective and have fun with characters like Maleficent.

''But I would like to focus more on writing and directing and above all I would like to focus more on my work with the UN.''

While Angelina enjoyed working on 'Maleficent', she found playing the titular character tough because of the transformation it required.

She explained in an interview with Britain's OK! magazine: ''It was so much fun but hard at first. As an actress, I do film, not theatre, so I don't naturally have that voice. I had to embrace my silliness.

''I think it's a beautiful story and there's a lot of depth to it and we got a little crazy and had a lot of fun. I hope that resonates and people are entertained by it.''
