Gilroy made his directorial debut with the thriller Nightcrawler (2014), which starred Jake Gyllenhaal, Rene Russo, and Riz Ahmed. Gilroy also wrote the script, which he conceived in 1988 after reading the photo-book Naked City, a collection of photographs taken by American Photographer Weegee of 1940s New York City residents at night. Gilroy did not begin writing the script until he moved to Los Angeles two years later, when he recognized an abundance of violent stories on television news. According to Gilroy, he considers the film to be a success story about a modern equivalent of Weegee, and a cautionary tale about the risks posed by capitalism. Nightcrawler was well received by the press on release, as was Gilroy's script, for which he was nominated for Best Original Screenplay at the 87th Academy Awards, and won Best Screenplay at the 30th Independent Spirit Awards. At the Independent Spirit Awards, Gilroy closed his acceptance speech by lamenting the proliferation of superhero films in Hollywood.
