In a movie filled with mind games, the ending of Paul Thomas Anderson's classic is its most memorable. Eli Sunday (Paul Dano) comes to Daniel Plainview (Daniel Day-Lewis) in hopes of selling him land for oil. Plainview agrees, but only if Eli, a preacher, denounces his faith. Sunday does, but then Plainview reveals the land is worthless as the oil has already been taken from it. This leads to a confrontation that ends with Plainview killing Sunday with a bowling pin. The last line of the movie is Plainview shouting, "I'm finished!"
