Thrillers take place mostly in ordinary suburbs and cities, although sometimes they may take place wholly or partly in exotic settings such as foreign cities, deserts, polar regions, or the high seas. These usually tough, resourceful, but essentially ordinary heroes are pitted against villains determined to destroy them, their country, or the stability of the free world. Often in a thriller movie, the protagonist is faced with what seem to be insurmountable problems in his mission, carried out against a ticking clock, the stakes are high and although resourceful, they face personal dilemmas along the way forcing them to make sacrifices for others.
