In the "Dark Knight" graphic novel by Miller, the Joker slaughters the audience of a television talk show with gas. A part of the Batman video game called "Arkham City" takes place in an abandoned movie theater (The Monarch, outside of which Bruce Wayne's parents were killed). Bruce Wayne's drive to become Batman arose from witnessing the deaths of his parents, Thomas and Martha Wayne, at the hands of small-time criminal Joe Chill, who shot and killed them after they had left a theater. There are general parallels to the Colorado shooting, "The Dark Knight" and the comic book character: The Christopher Nolan-directed "Dark Knight" trilogy has been more dark than that of typical superhero films, taking a cue from the comic book series published by DC Comics, including "Detective Comics" and writer Frank Miller's gritty 1986 take on the character, "Batman: The Dark Knight." By Hollywood standards, the Batman movies are more grim than bloody. In superhero movies, violent attacks on the public by villains are key components of many plots, including "The Avengers" and "The Amazing Spider-man," both in theaters now.
