Writer-director Paul Thomas Anderson steps outside his contemporary world of dysfunctional Angelenos to explore a very different dysfunctional man - an oil pioneer whose trailblazing spirit is equaled only by his murderous ambition. There Will Be Blood is Anderson’s loose adaptation of the novel Oil! by Upton Sinclair, and it focuses its attentions on Daniel Plainview (Daniel Day-Lewis), a miner who happens upon black gold during a disastrous excavation that ends in a broken leg.
