1. 'The Dark Knight'
A Batman movie is often only as good as the main villain. In 1997, Batman and Robin was hobbled by Arnold Schwarzenegger making an absolute fool out of himself as Mr. Freeze, while Michelle Pfeiffer's Catwoman seriously elevated 1992's Batman Returns. None of them can compare to Heath Ledger's Joker in 2008's The Dark Knight. The fact he died so soon after shooting certainly made the character seem more dramatic, but even if he'd lived it's likely he would have won an Oscar for Best Supporting Actor.
