Angelina Jolie has reportedly lost a lot of weight. The actress was recently seen at the premiere of her film "Unbroken," in Sydney, Australia, looking fragile in an off shoulder gown. Brad Pitt's wife channelled a monochrome fish tail hem gown by Gucci. To keep her thin frame in focus, Jolie wore bare minimum accessories. She only added a pair of diamond stud earrings and a bracelet.

A few days before the premiere, on 14 November, the "Tomb Raider" actress appeared in a super slim avatar at the 2014 Hollywood Film Awards at the Palladium. She tied her chestnut tresses in a classy chignon and accentuated her eyes with heavy eyeliner. Keeping with the off-shoulder trend, Jolie wore a black strapless gown.

Pitt's wife has lost a lot of weight over the years. Since her "Tomb Raider " days she has been reportedly working to sculpt her body. She is a yoga freak and does kickboxing to enhance her stamina, according to Healthy Celeb.

Moreover, while directing "Unbroken" Jolie also hired a new Australian fitness expert Luke Hines. He has been guiding her fitness and nutrition routine, according to The Daily Mail. As far as the actress' diet is concerned, she believes in having low calorie, high protein food.

Meanwhile, Jolie's film "Unbroken" is creating an Oscar buzz. Just like her husband Pitt's film "Fury," the film is a war drama based on a real life hero, Olympian-turned-WWII soldier Louis Zamperini. It has been inspired from a 2010 non-fiction book by Laura Hillenbrand, "Unbroken: A World War II Story of Survival, Resilience, and Redemption."

"It was an extremely moving experience to watch someone watching their own life... someone so physically strong... and they are at the stage where their body is giving up. And yet we laughed together, and talked about his mom," said Jolie about directing the film, according to US Daily.

"Unbroken" stars Jack O' Connell in the lead role and will open in theatres in December.
