Angelina Jolie has always been a cool celeb in our eyes but now she's proved that she's also a pretty rad mum too, after asking she and Brad Pitt's eldest son Maddox to help her on a very special project. 

It's no secret that the 40-year-old actress has swapped her role in front of the camera lens for a seat behind it, focusing all of her talent and efforts on directing. And she's proving to be a natural at it. 

After receiving rave reviews for her wartime biopic Unbroken, Ange has since gone on to direct her real life husband in the upcoming film By The Sea, in which she also stars. Now, her next directorial project has been revealed and this time, the subject is even more sentimental to the star. 

As a UN ambassador, Ange has campaigned against crimes of humanity for years, and her latest film will allow her to explore and shed light on one of the most terrifying ordeals of the 20th century. The film, entitled First They Killed My Father: A Daughter Of Cambodia Remembers will be a true-life drama based on the memoirs of Cambodian author Loung Ung. 

The film will delve into the horror that unfolded when Khmer Rouge took power in Cambodia in 1975, during which almost two million Cambodians died in a four-year-long reign of terror, during which the author Loung was forced to leave her family home to be trained as a child soldier while her siblings were sent to labour camps. Intense? Definitely. Emotional? A dead cert. But for Angelina, it will be a moving journey in more ways than one. 

To help her direct the film, which is being funded by Netflix, Angelina has asked her 13-year-old adopted son Maddox, who hails from Cambodia, to help her direct the feature. While it's no doubt an amazing opportunity for the teen, we can imagine that working on a subject matter so close to his heart and heritage will be all the more inspiring for him. 

Speaking of the film and the story of Loung Ung, Angelina said, 'I was deeply affected by Loung’s book. It deepened forever my understanding of how children experience war and are affected by the emotional memory of it. And it helped me draw closer still to the people of Cambodia, my son’s homeland. It is a dream come true to be able to adapt this book for the screen, and I’m honoured to work alongside Loung.'

'Films like this are hard to watch but important to see,' Angelina explained. 'They are also hard to get made. Netflix is making this possible, and I am looking forward to working with them and excited that the film will reach so many people.'

It's an opportunity that Angelina has been trying to make happen for years, as Loung Ung revealed in the same statement. Speaking of the adaptation of her memoirs, she said: 'Angelina and I met in 2001 in Cambodia, and immediately, I trusted [her] heart. Through the years, we have become close friends, and my admiration for Angelina as a woman, a mother, a filmmaker and a humanitarian has only grown. It is with great honour that I entrust my family’s story to Angelina to adapt into a film.'
