Shortly after making Punch-Drunk Love (2002), Paul Thomas Anderson had started work on his next film, which was originally to have been about two feuding families. However, Anderson was having trouble with the screenplay, it wasn't working at all, so he took a holiday to London, England. He soon found himself homesick, but after a chance visit to a bookshop, he saw a book with a cover illustration of an oilfield in California, around the turn of the 20th Century. The book by Upton Sinclair was called Oil! Originally published in 1927, with the book, Anderson read it, and he had found a perfect source for a film, he began work on a screenplay, only adapting the first 150 pages of the 560 page book, the book dealt with socialism, which Anderson all but removed. The film woud be different from the book, and it would prove to be quite different from what Anderson has done in his previous films. There Will Be Blood is a modern day equivelant of an old Hollywood studio-system epic of the 1940's and 50's, plus it's one of the best films made in recent years...
The film starts in 1898, where silver propector Daniel Plainview (Daniel Day-Lewis) discovering traces of crude oil within one of his silver claims, jump 4 years later, Plainview now has a small drilling company, and he adopts an orphaned young boy of one of his worked killed in an accident on the job. By 1911, Plainview is one of the most successful oilmen in America. Following a tip from a young man called Paul Sunday (Paul Dano), that there's oil near his family ranch in Little Boston, California. Plainview heads out there, and sets out to bargain the land from the Sunday family, he ends up brokering a deal with Paul's twin brother Eli Sunday, (also Paul Dano), who wants his own church, the Church of the Third Revelation, with Eli as a faith healer, which Plainview is scornful off. But, he's got his eye set on the "ocean of oil" beneath his feet. But, his greed for more land and more oil alienates him from his co-workers and the people closest to him.
Words are hard to describe how emotionally gripping and visually compelling this film is, but all I will say is that it is Paul Thomas Anderson's best film to date, (yes, better than Boogie Nights (1997) and Magnolia (1999), which is saying something!!) He creates a dark mood from the outset, even for the first 15-20 minutes, not one work of dialogue is spoken, but sometimes, people can say a whole lot without uttering a single word. Anderson captures the era well too, and even when accidents occur, this was a time before health and safety regulations that go around today. But, one major accident leaves Plainview's adopted son H.W. (Dillon Freasier) deaf. H.W. is the movies emotional heart, he is used as a pawn in Plainview's dealmaking, Plainview wants to set the image of a familyman done good, which would make people sell their land to him. One sign of Plainview's eventual overpowering greed.
Even Plainview is united with a long-lost half-brother Henry (Kevin J. O'Connor), this has Plainview abandoning H.W. in favour of Henry, which is a hard scene to watch. And then there's Eli Sunday, who is revealed could be just as greedy and manipulative as what Plainview is. He sees himself as a faith-healer, something Plainview doesn't believe, and sees Sunday's energetic and vivid faith healing as fake, only putting faith and hope into the people of Little Boston. The relationship between Plainview and Sunday is a difficult one, but it provides the films backbone.
Daniel Day-Lewis is on top form throughout this film, starting off as oil-prospector done good, he succumbs to greed and paranoia throughout the film. Whilst doing the film, he and Anderson would watch John Huston's The Treasure of the Sierra Madre (1948), another tale of greed and paranoia, (the opening sequence of Plainview looking for Silver mirrors the scene of Humphrey Bogart's Fred C. Dobbs mining for gold. True, Day-Lewis looks like Bill The Butcher from Gangs of New York all over again, but this is a different character all together, this a man who is determined to get what he wants, he won't let reluctant sellers stand in his way, another sign of his decline into madness. But, the breakout performance of the film is Paul Dano as Paul and Eli Sunday, one man who led Plainview to the oil on the family ranch, and the other as a man who stood in his way. Dano was in turn a last minute replacement for Kel O'Neill, who got alot more than he bargained for when he was up against Day-Lewis' legendary Method acting. Dano was used to it, having worked with Day-Lewis on The Ballad of Jack and Rose (2005), compared to Plainview's powerful and demeaning force of nature, Eli Sunday is a more calm and restained figure, but at the end of the day, he's a wretched, two-faced preacher, maybe just as bad as Plainview. But, it does end with a powerful and engaging duel of words between the two.

If Magnolia was Paul Thomas Anderson's love letter to Robert Altman, then this is a letter to the works of Stanley Kubrick, even emulating some of the late masters way of shooting. There's even touches of John Huston and Terrence Malick within the film. It's a film that remains with you long after you've seen it, it's emotionally exhausting but it's worth it, Day-Lewis is on fine form throughout this film, the combination of him and Anderson working together was an irrestitable combination, and Anderson brings the best out of him, this is a man who doesn't start out greedy, but the obsession for more oil makes him greedy. The title of the film may sound biblical, but stories of greed have been around since the days of the bible, it's a meditation on greed, but it works. Robert Elswit's cinemtography and Radiohead's Jonny Greenwood's score are the perfect additions to a perfect film. Whatever Anderson does next will be eagerly awaited...
