Before the Golden Globes, many assumed that Kathryn Bigelow's drama "Zero Dark Thirty" was beelining for The Best Picture Oscar. However, after Ben Affleck's "Argo" took home the Globe -- and the SAG award, we could have a bit of an upset on our hands.

In honor of this year's Academy Awards, let's take a look at the biggest upsets in Oscar history.
