Sorry, but Heath Ledger didn’t improvise that Joker scene

The Dark Knight came out way back in 2008 but is remembered to this day as one of the best Batman movies ever made, one of the best sequels ever made, and to some one of the best films ever made, point blank. A lot of thanks is due to actors Christian Bale, who played the duel role of Bruce Wayne/Batman with the perfect mix of suave smarminess and gravel-voiced intensity; and Heath Ledger, who was terrifying and hilarious as the Joker.
