Before this post, did you know what Millard Fillmore looked like? Or that he and Alec Baldwin possess an uncanny resemblance? Many of us are ignorant about historical figures' physical appearances, despite the abundance of information at our fingertips. Which is why Biography's gallery of famous lookalikes is fascinating! Check out some of them after the cut!

Who'd have thought that Jack Black and Paul Revere have something in common, or that George Clooney resembles an iconic revolutionary?

What do you think of the gallery? Can you think of any other historical/modern celebrity lookalikes?
