Production Development Following the critical and financial success of Batman Begins (2005), the film studio Warner Bros. Pictures prioritized a sequel. Although Batman Begins ends with a scene in which Batman is presented with a joker playing card, teasing the introduction of his archenemy, the Joker, Christopher Nolan did not intend to make a sequel and was unsure Batman Begins would be successful enough to warrant one. Christopher, alongside his wife and longtime producer Emma Thomas, had never worked on a sequel film but he and co-writer David Goyer discussed ideas for a sequel during filming. Goyer developed an outline for two sequels, but Christopher remained unsure how to continue the Batman Begins narrative while keeping it consistent and relevant, though he was interested in utilizing the Joker in Begins grounded, realistic style.
