Writing romantic letters to each other sounds so old school in this era of Internet and mobile phones but not for the newly-wed couple Angelina Jolie and Brad Pitt. Angelina revealed in her recent interview that she and her husband Brad wrote "war" letters to each other sometime back when they both were busy shooting war movies in different parts of the world.

Both Jolie and Brad were busy shooting for their respective war-themed movies. While Jolie was busy shooting as a director for "Unbroken" in Australia last year, Brad Pitt at that time was in England shooting for "Fury," where he plays the character of American tank commander in Germany during the era of World War II. Both Jolie and Pitt were doing movies from the World War II era so had quite a lot of common stuff to explore.

"It was interesting that we had different parts of the war, different theatre of the same war at the same time. We wrote letters back and forth, 1940s style," Jolie said, according to smh.com.au.

The content of the letters did not discuss the technique of war films but about Brad as a man, revealed Jolie calling her husband a "great man." The actress and director then appreciated Brad for "the choices he makes with our family, our children, the way he treats me and the values he holds."

Jolie is of the opinion that her movie is about greatness of men. "These are the things I brought to the film, and what I felt I understood about men, and what I love about men," revealed the actress, adding that she wants this generation to be reminded of "men and their greatness."

The actress and the team of "Unbroken" is currently in Australia to promote the movie that has been made on a budget of $65 million. The movie is based on the life of late Olympic runner Louis Zamperini who was taken as a prisoner by the Japanese forces during World War II. The actress called Zamperini a "great and an extraordinary man" who asked Jolie to make the film on his life to show to the world how extraordinary everyone else is. "Unbroken" opens in theaters on Jan. 15, 2015.
