The two-and-a-half minute clip depicts a love affair between a Serbian man and a Bosnian woman, set against the gritty backdrop of the 1992 Bosnian War.
Filming in Bosnia and Hungary, first-time director Jolie, 36, opted to cast local actors Goran Kostic and Zana Marjanovic in the leading roles, rather than Hollywood A-listers. She also wrote and produced the movie, which was shot both in English and the local Bosnian-Croatian-Serbian language, BHS.
In the Land of Blood and Honey will be released in the U.S. on Dec. 23.
