Ledger did a hell of a job making this character one of the most iconic in cinematic history, and sadly, he didn’t live to see the production as a whole. What he did get to witness however, were the opening scenes of the film before his death.

Ledger was given the early sneak peek of the bank heist scene at the start of the movie after Nolan had edited the movie himself. Producer, Charles Roven, stated that Ledger loved the scene so much he watched it again twice more.

I would venture a guess that he knew in just watching that first opening scene that together something special had been created.
