Sidney Bartlett (July 10, 1900 – May 29, 1978, born Sacha Baraniev)[a] was a Ukrainian-American author and screenwriter and producer of Hollywood films.

Sy Bartlett was born Sacha Baraniev on July 10, 1900, in the Black Sea seaport of Mykolaiv in the Russian Empire (now Ukraine).

Of Jewish descent, Bartlett was strongly anti-Nazi, once striking an employee of the German consulate in the face during an argument in a nightclub.

However, he was not interested in making training films and used connections to meet Beirne Lay, Jr., who was on the staff of Army Air Forces Brig.

[2] Following World War II, Bartlett returned to Hollywood and joined 20th Century Fox as a writer.
