Brad Pitt's production company, Plan B, hired Monahan to write an adaptation of Hong Kong director Andrew Lau's gangster film Infernal Affairs. Monahan respun Infernal Affairs as a battle between Irish American gangsters and cops in Boston's Southie district, and Martin Scorsese directed the completed screenplay under the title The Departed for Warner Bros. Monahan's work on the film would later earn him two Best Adapted Screenplay awards, from the Writers Guild of America and the Academy Awards. Working scripts through production and after Kingdom of Heaven was the first of Monahan's screenplays to be produced into a film. Monahan had negotiated a production write-through contract for Kingdom of Heaven, which allowed him to be present on the movie sets to make modifications to the shooting script during production. It was poorly received by critics when it was released in theaters in 2005. Kingdom was critically reappraised when it was released on DVD in the form of a director's cut that contained an additional 45 minutes of footage previously shot from Monahan's shooting script. Some critics were pleased with the extended version of the film. Monahan's second produced screenplay was The Departed, an adaptation of the Hong Kong action film Infernal Affairs. Jack Nicholson, one of the leads in the film, influenced the screenplay. "I had written the role as a post-sexual 68-year-old Irishman. Jack is post-sexual exactly never," Monahan said later. "What Jack did is great. Did he change the words? Not any of the good ones." Monahan received considerable praise from critics when the film was released in theaters, in 2006, and was applauded for accurately depicting the city of Boston. Monahan used his intimate knowledge of the way Bostonians talk and act, learned from his youth spent in the many neighborhoods of Boston, to create characters that The Boston Globe described as distinctly indigenous to the city. By the end of 2006 The Departed had won many critics' prizes. Monahan was honored by The Boston Society of Film Critics with the award for best screenplay, by the Chicago Film Critics Association for best adapted screenplay, and by the Southeastern Film Critics Association with another best adapted screenplay award. Monahan took an unusual route for a screenwriter and hired a publicist to run a campaign promoting his screenplay during awards season. Monahan ended up winning two Best Adapted Screenplay awards for The Departed, from the Writers Guild of
