London: Actress-turned-director Angelina Jolie has been working on a story inspired by her late mother but says she will never show the project to anybody.

The 36-year-old actress stepped behind the camera to make her directorial debut with 'In The Land Of Blood And Honey', a film she penned herself about a romance between a Serbian soldier and a Bosnian woman.

Now, Jolie says she has also written a tale about her beloved mum Marcheline Bertrand, who died in 2007, but refuses to make it public, reported a website.

"I've also written a story about my mother after she passed. They are things I will never show anybody but it is nice to spend time with people and characters in this private world," she said.

The Hollywood star recently admitted that she has also put pen to paper for a script about Afghanistan, but maintained she lacks the "confidence" to put it into production.
