Every Best Actor Oscar Movie Winner Of The 21st Century Ranked

Who should have won: Daniel Day-Lewis - There Will Be Blood.

Here it is: The greatest Best Actor performance of the century, and one of the finest performances in cinema history. It sounds hyperbolic, yet it's impossible to deny the overwhelming power of Daniel Day-Lewis's turn as vicious oilman Daniel Plainview.

Backstabbing, murderous, tenacious, selfish and cruel, Day-Lewis commands every second of Paul Thomas Anderson's macabre drama, embodying the horrific underbelly of capitalism and greed with a performance that's at once surprisingly tender and deeply unsettling.

Over the years, Daniel Day-Lewis has given us some of the strongest, strangest, most unforgettable performances you're ever likely to see, and his turn as Plainview stands as his crowning achievement. We'll be talking about it for years to come.
