The Most Famous Line in 'The Dark Knight' Wasn’t Written by Christopher Nolan — and It Still Bothers Him

It takes a special kind of canonical classic to feature a line of dialogue so memorable that anyone could identify what movie it comes from without any context. "You either die a hero, or live long enough to see yourself become the villain," uttered by Harvey Dent (Aaron Eckhart) in The Dark Knight, fits the bill. In what is likely to remain his culturally definitive and most popular movie, Christopher Nolan, for better or worse, changed the film landscape forever by making a superhero movie feel like an American epic about crime, justice, and society's belief in costumed vigilantes as religious dogmas.
