Thriller films typically feature a protagonist who encounters an antagonist seeking revenge with a secret motivation. Fast-paced editing techniques like quick cuts and cross-cutting are used to build tension during climactic scenes, along with low key lighting, shadows, and a tension-building musical score. Common props include weapons like knives and guns, and the victim is usually female.
