 Screenwriter Charles Edward Pogue (qv) originated the idea of  remaking _Fly, The (1958)_ (qv), and wrote the script. When  David Cronenberg (qv) was hired as director, one condition was  that he be able to extensively rewrite the script. Cronenberg  substantially altered the characters (and their names), the  dialogue, and much of the plot. However, key details from Pogues  script (the fusion of man and fly and details of the metamorphosis)  were retained.
