There Will Be Blood (2007)

There Will Be Blood (2007) delivers the most unflinching portrait of capitalist ambition, with Daniel Day-Lewis's Daniel Plainview crushing rivals across a 20-year oil boom. His ruthless methods yield a 300% profit margin on his first strike, outperforming #7 The Wolf of Wall Street's fraudulent gains through sheer determination. The film's $25 million budget earned $76 million, a 204% return that mirrors Plainview's own unyielding efficiency.
