George Clooney 'ER' Bloopers: Star Flubs Supercut

George Clooney, already an Oscar-winner, won the Golden Globe for Best Actor in a Drama on Sunday night. He's now one of the biggest movie stars in the world, but before he made it on the big screen, he broke out as the star of "ER."

The world swooned over his Dr. Doug Ross, and with good reason: handsome and compassionate, he was the guy everyone would want to treat them in a pinch. Then again, they never saw the outtakes.

Check out this blooper reel of Clooney's time on the NBC medical drama, which includes all the crack ups, mess ups and laugh out loud moments you didn't get to see on TV.
