Many reports said that "Unbroken" director Angelina Jolie has lost a few pounds after shooting her latest film.

Inquistr said that her weight loss secret is expensive. But why?

"Unbroken" stars including Japanese actor Miyavi, Jack O'Connell and Finn Wittrock appeared on a live interview with HuffPost.

The Japanese star (known as a rockstar) again dropped a bomb about their director Jolie, revealing how she got thin. He said, "It was surprising how much she trusted me, all of us, on the set. She was so determined. I was also surprised how skinny she got. You know, she was not eating much. I felt so bad I was the only one who got fat during filming."

That's why Inquistr said that the secret of Jolie's weight loss is expensive as the publication is referring to the budget of the drama film.

On the previous reports, the Japanese actor reportedly couldn't stop crying and got sick during the shooting of the drama flick. He told Vanity Fair that "Salt" actress advised him "to immerse himself into the mindset of a man accustomed and desensitised to violence."

"It was awful torture for me to hate the other actors. I had to have hatred for them. When I had to beat them, I had to think about protecting my family. At the same time, I didn't want to be just a bad guy. I wanted to put humanity in this role. [Matsuhiro] was both crazy and sadistic, but also weak and traumatized," Miyavi told VF.
