Paul Thomas Anderson (Boogie Nights, Magnolia) ditches his ensemble style to (loosely and magnificently) adapt an obscure Upton Sinclair novel. Daniel Day-Lewis eats up the screen as Daniel Plainview, a scrappy misanthrope who builds an oil empire with his bare hands in turn-of-the-last-century Texas. Like Citizen Kane and Giant before it, this is epic American mythmaking. Unlikable as he may be, Plainview is an icon. There Will Be Blood follows him throughout the decades as he amasses his fortune, adopts a son, founds a town and makes an enemy of the church. A gritty, roughnecked portrait of American industry, religion and politics. 158 minutes R.
