There Will Be Blood

There Will Be Blood is a 2007 American drama film written, co-produced, and directed by Paul Thomas Anderson. The film is loosely based on Upton Sinclair's 1927 novel Oil!. It tells the story of a gold miner-turned-oilman on a ruthless quest for wealth during Southern California's oil boom of the late 19th and early 20th centuries. It stars Daniel Day-Lewis and Paul Dano.

The film received significant critical praise and numerous award nominations and victories. It appeared on many critics' "top ten" lists for the year, notably the American Film Institute, the National Society of Film Critics, the National Board of Review, and the Los Angeles Film Critics Association. Day-Lewis won Oscar, BAFTA, Golden Globe, Screen Actors Guild, NYFCC and IFTA Best Actor awards for his performance. The film was nominated for eight Academy Awards including Best Picture, winning Best Actor for Day-Lewis and Best Cinematography for Robert Elswit.

In late 2009, it was chosen by Lisa Schwarzbaum of Entertainment Weekly, Peter Bradshaw of The Guardian, Peter Travers of Rolling Stone and Michael Phillips of the Chicago Tribune and At the Movies as the best film of the first decade of the 21st century.
