Dark Knight Movie Facts, Easter Eggs and hidden details

Contrary to internet myth the delay in the hospital explosion was not a fluke. It was part of the script and Heath Ledger practiced the Joker's reaction meticulously before they did it for real.

The Joker tells different stories about how he got his scars. In the comic, The Killing Joke, The Joker states, "sometimes I remember it one way, sometimes another..if I'm going to have a past, I prefer it to be multiple choice".

Christopher Nolan has said the look of the Joker in The Dark Knight (2008) was based heavily on the paintings of Francis Bacon which are famous for their depictions of violence and agony. Bacon's Figure with Meat is the painting the Joker spares in Batman (1989)

One character is a possible nod to the villain The Riddler. Coleman Reese (Joshua Harto) deduces Batman's identity with little effort, like The Riddler has in the comics. He's also addressed as "Mr. Reese," a homonym of mysteries like how the Riddler is E. Nygma/enigma

Batman says that the sonar device is "null-key encrypted". This was added as a joke since it actually means that there is no encryption.

I've watched this movie countless times since it's release, but just noticed that in The Dark Knight (2008), Joker is wearing a sticker from Harvey's campaign

The first time Harvey Dent is doing something unlawful, which is threatening someone at gunpoint, only half of his face is lit indicating his transformation into Two-Face later on in the movie.

The opening heist scene has multiple 'clowns' killing one another off with the Joker last standing. The second major scene has Batman fighting criminals and multiple 'batmen'. Each scene symbolizes the development and struggle of the two main characters.

During the Joker interrogation scene, the Joker makes the Batman choose between Harvey and Rachel, and actually explains to the Batman that he's going to have to choose who dies. By choosing Rachel (thinking he'll be saving her), hes choosing her to die instead.

The Joker says he hates schemers and claims he's a man without a plan. Later on during the boat scene, he is shown reading his monologue from a notebook, highlighting his hypocrisy

Have you ever wondered how Two-Face managed to slip into Maroni's limousine unnoticed? If you watch closely, you can see him take out a henchman as Maroni and his assistant round the car.

The Joker manages to get a peek of the commissioner's watch to determine how much time he has left until the timers run out.

When the Joker crashes the penthouse party and fires a shell in the air, everyone flinches but Alfred. He just stands there like, "you fking clown I burned down a forest once."

The video the Joker makes with the Batman impersonator (which Heath Ledger directed) is carefully set up to mimic the painting the Joker saves from being vandalized in Tim Burton's Batman (1989).

Right after Bruce Wayne tells Rachel that Gotham needs a hero with a face, Harvey Dent appears. As he approaches them half of his face gets covered by (fore)shadow.

At the beginning of the movie, the bank robbers quickly learn that the bank vault is protected by high voltage. Later, one of the robbers can be seen using his shoes on the dial to avoid being shocked.

During their first fight in the sewer, Bane gives away that he isn't the child that escaped The Pit by telling Batman "I didn't see the light until I was already a man..."

's joker(Heath Ledgar)wore same mask that joker(Cesar Romero)wore on the first Batman series(1966)when he showed up in the bank.

During the masquerade scene, everyone is wearing a physical mask except Bruce Wayne and Miranda Tate. Wayne (Batman) and Tate (Talia al Ghul) are the masks to their real personas.

Atthe end of the film there's a statue of Batman in his memory. In the same scene, Nolan arranged his crew in a formation of a clown's smile, tribute to Ledger's Joker.

The seating arrangement is a portrayal of the Joker's smile to pay tribute to Heath Ledger.

During the scene where the Joker visits Two-Face in the hospital, the nametag on his nurse's uniform reads, "Matilda." It's a tribute to Ledger's daughter, Matilda, who was just two years old at the time of her father's death.

As the officers in the room applaud Gordon's Commissioner announcement, Ledger, unscripted begins to slowly clap - never changing his facial expression. It was just a simple improvisation but one that was unsettling and darkly brilliant

The color of the cloth used to cover the Batman statue is the same blue as the ones that show up in the golden age Batman comics

The character of Coleman Reese is an allusion to The Riddler, who attempts to reveal the identity of Batman. Much like Edward Nygma whose name sounds like "enigma" (as in E. Nygma), Mr. Reese sounds like "mysteries".

The robber disabling the silent alarm says "That's funny, it didn't dial out to 911 it was trying to reach a private number." The private number was for the mob, so they would know their money was being stolen before the police would.

When Harvey Dent is talking to the press, the camera flashes only light up half of his face, foreshadowing his sinister alter ego

Batman hands over a mini mine to Detective Blake to throw at the entrance of the sealed manhole which causes a small explosion, because it was to warn the cops stuck on the other side for a bigger explosion to be caused by the Batpod's missile.
