10 Subtle Comic Book Movie Details You Definitely Didn't Notice

5. Don't Hit A Guy With Glasses - Batman

At the end of Tim Burton's delightfully dark Batman, The Joker seemingly attempts a little levity as he faces down his cowled enemy who seems intent on ending his reign of terror with pointed finality. As Batman closes in on him to deliver another blow, the bloodied Clown Prince of Crime says "hey, you wouldn't hit a guy with glasses, would ya, huh?" and puts a pair on.

Batman ignores him, inevitably, but this is no throw-away gag.

It actually calls back to an episode of the 1966 Batman TV show, in which Batman establishes to Robin that he has a strict code of conduct when it comes to bespectacled enemies. Different times.
