10 Cool Easter Eggs You Didn’t Know Were Hidden On DVD & Blu-Ray
8. The Jokerized Version - The Dark Knight
The Easter Egg: The Dark Knight is famous for its marketing campaign, which, at the time, was one of the most extensive in existence.
A big part of the campaign was the use of Heath Ledger's Joker, and iconography associated with the character.
Joker cards were hidden in comic-book stores. An "I Believe In Harvey Dent" website was defaced with the Joker's signature red smile and dark eyes. The marketing team even 'Jokerized' several one-dollar bills by scrawling over the image of George Washington at their centre.
This continued for the film's home-media release, which featured a special version of the film's third theatrical trailer.
The trailer plays as normal, but it's also been 'Jokerized', with graffiti, text and scrawled drawings appearing over the top.
How To Find It: Pop in Disc 2 of your Blu-Ray and make your way to the 'Trailers And More' section. Click on 'Trailer 3'. When the trailer starts playing, enter these numbers in this order (slowly), using your keypad: 5, 6, 5, 3, 7.
The trailer will restart and the alternate version will play.
