Angelina Jolie and Brad Pitt kept their romance alive while shooting films on two different continents last year (13) by sending each other handwritten love letters.
The Salt star was directing Unbroken, a biopic about Olympic athlete and World War II hero Louis Zamperini, in Australia, while her fiance Pitt was on the other side of the world in London, shooting his own Nazi war film, Fury.
The Hollywood actors decided to embrace the time period their onscreen dramas were set in and shunned modern technology in favour of writing sweet notes to one another by mail.
Jolie tells Australia's TV Week magazine, "He was supportive from a distance, and it was quite romantic in a way.
"We decided to be of that time, when we could imagine he was in the European theatre and I was in the Pacific theatre, and we wrote handwritten letters to each other that were very connecting for us, thinking of the people that were separated for months, if not years, at a time back then."
The couple has been engaged since 2012.
