Batman: The Long Halloween - in Other Media

In Other Media

The Long Halloween was one of three noted comics that influenced the 2005 feature film Batman Begins, the others being Batman: The Man Who Falls and Batman: Year One. The film's sequel The Dark Knight adapted many elements of this story, the setting of Batman, Gordon, and Harvey Dent talking on the roof of the Gotham City Police Department is taken from this story and used in The Dark Knight, as is Gordon's line "he does that" to Dent when Batman disappears from the conversation in the middle of Dent's sentence. In the comic, Harvey Dent has acid thrown on his face during court, but in the film a witness draws a gun on him (though this is not how he becomes Two-Face in the film). The comic also depicts Dent and Batman discovering mountains of cash and destroying it, while in the film it is the Joker who destroys a pile of the mob's cash. Similar to the scene where the Dents have their house blown asunder, the Joker is behind setting up explosives for Harvey and his loved one in the movie, with the role of Gilda replaced by Rachel. Harvey Dent succumbing into the tragic fate of "Two-Face", his obsession with the mob, is taken directly from the book and adapted onto screen. Unlike the book, Sal Maroni is not "directly" responsible for Harvey's facial scars, in the movie the Joker and corrupt policemen on Maroni's payroll are responsible for carrying it out. But Maroni is also considered the culprit as he 'unleashed' the Joker. This is the version Dent chooses to believe, as he is later seen confronting Maroni, holding him responsible for the Joker's actions. The scene where Batman disguises himself as a helmeted bodyguard to ambush Holiday is mirrored in The Dark Knight, with the decoy bodyguard being Gordon, the 'transfer' being Harvey instead of Maroni, and the target being the Joker instead of Holiday.

In the 2011 video-game Arkham City, Catwoman's third DLC costume portrays the one in Long Halloween.
