Se7en is the film about two cops pursuing a serial killer whose murders represent the seven deadly sins.
Released in 1995, the film follows veteran detective William Somerset and his newly transferred partner, David Mills. They investigate a series of elaborate murders in an unnamed, rain-soaked American city, with each crime designed around a particular sin, including gluttony, greed and pride.
David Fincher directed Se7en from a screenplay by Andrew Kevin Walker. Morgan Freeman played Somerset and Brad Pitt played Mills, whose contrasting personalities shape the investigation: Somerset is experienced and cautious, while Mills is younger, impulsive and determined to prove himself.
The title is commonly written as Se7en, although the film is also referred to as Seven. It is often classified as a crime thriller or psychological thriller rather than straightforward horror. Its bleak atmosphere, disturbing crime scenes and emphasis on moral corruption are why it frequently appears in discussions of serial-killer and horror cinema.
