Someone Noticed A Hilarious Detail About 'The Dark Knight' Batman Movie

It's been nearly a decade since The Dark Knight aired in movie theaters, just to make you feel even more old. And while we've all probably watched the movie about ten times, you may not have noticed the hilarious detail that has Twitter in hysterics.

The scene in question is when the Joker, played by Heath Ledger, sneaks into a hospital dressed as a nurse to try and kill a wounded Harvey Dent, played by Aaron Eckhart. Just look at Dent's reaction to the Joker...

HOW DID NO ONE NOTICE? This is the greatest piece of acting in the history of cinema. Twitter seemed to agree...

Others defended the scene.

This is hilarious.
