* Split: The city of Split was used for many of the urban scenes, including the iconic scene where the character of Lieutenant Chris Burnett (Owen Wilson) escapes from the Serbs.
* Dalmatia: The rugged coastline and mountainous terrain of Dalmatia provided the backdrop for many of the film's action sequences.
* Makarska Riviera: This coastal region was used for scenes involving the Croatian coastline and the Adriatic Sea.
The film also used some sets built in Los Angeles, California, for interior scenes and certain action sequences.
However, the majority of the film was shot on location in Croatia, capturing its stunning scenery and creating an authentic backdrop for the war-torn setting.
