Joseph Kony has quickly become a household name ever since charity group Invisible Children took their Kony 2012 campaign viral with a 30-minute film on March 7. And now, celebs are helping spread the word too.

The video depicts the terrible conditions children are suffering through in Uganda and aims to raise awareness about Kony's brutal role in all of it. It's a painstaking reminder of how just one person can create so much evil. Several of Hollywood's biggest stars have tweeted the video out to their millions of Twitter followers, in the hope of making Kony famous enough to receive the justice he deserves.
