Constantine is a 2005 American superhero horror film directed by Francis Lawrence in his directorial debut. Written by Kevin Brodbin and Frank Cappello, it is based on DC Comics’ Hellblazer comic book. The film stars Keanu Reeves as John Constantine, a cynical exorcist with the ability to perceive and communicate with half-angels and half-demons in their true form. Its cast also includes Rachel Weisz, Shia LaBeouf, Tilda Swinton, Pruitt Taylor Vince, Djimon Hounsou, Gavin Rossdale, and Peter Stormare.

Constantine was theatrically released in the United States on February 18, 2005. It grossed $230.9 million worldwide against a production budget between $70–100 million, but met with a mixed reception from film critics. In Mexico, a scavenger recovers the tip of the spear that pierced Jesus Christ from a ruined church and, after becoming possessed, takes it to Los Angeles. There, cynical occult expert John Constantine exorcises a demon from a young girl after witnessing its attempt to come through her to Earth, something that should be impossible because of a treaty between Heaven and Hell. Suffering from terminal lung cancer, Constantine meets with the half-breed angel Gabriel to request an extension to his life in exchange for his work deporting Hell’s forces. Gabriel responds that performing good deeds for selfish reasons will not secure his way into Heaven.
