Universal Studios acquired the adaptation rights from Millar in 2004, and while the eventual script drifted from the comic book supervillain mythos from the original miniseries, Millar was content to see most of the comic's darker content was retained. Production began in April 2007, with filming in the Czech Republic, Budapest and the story's main setting, Chicago. Wanted was released on June 2008 to both critical and commercial success, with box office earnings of $341 million worldwide and reviews praising the fast pacing and stylized action scenes. Universal had interest in a sequel, which is currently in development hell.
