Silence of the Lambs tells the story of a young ambitious FBI profiler Clarice Starling as she pursues the serial killer Buffalo Bill with the help of convicted psychopath Hannibal Lecter.  While researching the book on which the film was based, author Thomas Harris spent days with the FBI's pioneering Behavioural Science Unit, questioning criminal profilers and immersed in the case-files of serial killers. Now, we reveal the movie's real-life inspirations: serial killer Ted Bundy who, like psychiatrist Lecter, evaded capture with his charming, young lawyer persona; Ed Gein, whose sickening crimes echo the movie exploits of Buffalo Bill; and a young female FBI agent who helped Harris create Agent Starling. We also explore how Silence of the Lambs revolutionised the make-up of the profession, inspiring many women to become profilers, and reveal chilling footage of one such female entrant interviewing Gary Ridgway, considered America's most prolific serial killer.
