William Scott Darling (May 28, 1898 – October 29, 1951) was a Canadian-born writer and a pioneer screenwriter and film director in the Hollywood motion picture industry.In 1914, Darling was hired by the Kalem Company of New York City to work at their California studios writing the scripts for the adventure film serial The Hazards of Helen.With the advent of sound film, he easily adapted to creating dialogue and wrote scripts for early "talkies" such as Fox's Trent's Last Case (1929) based on the E. C. Bentley novel and directed by Howard Hawks.A prolific and diverse writer, during the 1930s and 1940s, Darling wrote more than seventy screenplays that were used for major films and popular B-movie thrillers produced by American studios in Hollywood as well as in London.Among these were Universal's The Ghost of Frankenstein (1942) and Sherlock Holmes and the Secret Weapon (1943) that received critical acclaim and were considerable box office successes.
