to delete Gambol's subplot and have him killed off in the scene where the Joker originally simply mutilated him. After Ledger's death, Christopher Nolan decided not to recast the role out of respect for his performance, and initially was hesitant to make a third film. Warner Bros. president of production Jeff Robinov had hoped a third film would be released in 2011 or 2012. Nolan wanted the story for the third installment to keep him emotionally invested. "On a more superficial level, I have to ask the question," he reasoned, "how many good third movies in a franchise can people name?" Nolan said that he never even thought a third film was possible in the foreword for his book The Art and Making of the Dark Knight Trilogy. Nolan only agreed to a third film on the basis of finding a worthwhile story, fearing that he would become bored halfway through production if he discovered the film to be unnecessary. By December 2008, Nolan completed a rough story outline, before he committed himself to Inception. Later in December, Alan F. Horn confirmed that while discussions with Nolan about a third film were ongoing, no casting had been done, and Horn denied all such rumors. Before Nolan confirmed his involvement, Gary Oldman had said he was confident Nolan would return. Following the success of the Joker in The Dark Knight, studio executives wished for the Riddler to be included as the primary villain as he was considered a similar character and encouraged the casting of Leonardo DiCaprio. However, Nolan wanted the antagonist to be vastly different from the previous incarnations and committed to using Bane instead, citing the need for a character with a physical presence within the film. He was initially unfamiliar with the character's back-story, but pointed out the appeal of an archetype, labeling it as "the extreme of some type of villainy". When comparing the choice of Bane with the Joker, Nolan highlighted the Joker as an example of "diabolical, chaotic anarchy and has a devilish sense of humor", juxtaposing him against Bane, whom he likened to "a classic movie monster [...] with a terrific brain." Nolan has said that his draft of the script was inspired by Charles Dickens' 1859 novel A Tale of Two Cities, which centers around the French Revolution. This homage to Dickens was briefly illustrated by having Bane inconspicuously finger knit paracord in
