There Will Be Blood is a 2007 American epic drama film written and directed by Paul Thomas Anderson. The screenplay is loosely based on the 1927 novel Oil! by Upton Sinclair. The film stars Daniel Day-Lewis as Daniel Plainview, a silver‑prospector turned oil magnate, and Paul Dano as his adopted son, H.W. Plainplain. Supporting roles are portrayed by Kevin Bacon, Ciarán Hinds, and Dillon Freasier.
The narrative follows Plainview's ruthless pursuit of wealth during the Southern California oil boom of the late 19th and early 20th centuries, depicting his conflicts with local landowners, notably preacher Eli Sunday (Bacon). Themes explored in the film include capitalism, religion, family dynamics, and the moral decay associated with unchecked ambition.
Production on There Will Be Blood began in 2005, with principal photography conducted in various locations across the United States, including California, New Mexico, and Texas. The film's score, composed by Jonny Greenwood of Radiohead, incorporates a blend of orchestral and experimental elements and has been noted for its influence on the film’s atmosphere.
There Will Be Blood premiered at the Cannes Film Festival on May 20, 2007, where it won the prestigious Palme d'Or. It was subsequently released in the United States on December 26, 2007. The film received critical acclaim for its direction, screenplay, performances—particularly Day‑Lewis's portrayal of Plainview—and Greenwood's score. It earned eight nominations at the 80th Academy Awards, winning two: Best Cinematography (Robert Elswit) and Best Original Score (Jonny Greenwood). The film is frequently cited in lists of the greatest movies of the 21st century and has had a lasting impact on contemporary cinema.
