Question: Which female film director's career spanned more than one film era, Dorothy Arzner or Gurinder Chadha?
Context: Merrily We Go to Hell is a 1932 pre-Code film starring Academy Award winning actor Fredric March and Sylvia Sidney.  The film was directed by Dorothy Arzner.  The film's title is an example of the sensationalistic titles that were common in the Pre-Code era.  Many newspapers refused to publicize the film because of its racy title.  The title is a line March's character says while making a toast. Dorothy Emma Arzner (January 3, 1897 – October 1, 1979) was an American film director whose career in feature films spanned from the silent era of the late 1920s into the early 1940s.  In fact, Dorothy Arzner was the only female director working in the 1930s in the United States.  She was one of the very few women who established a name for herself as a director in the American film industry during this time. First Comes Courage is a 1943 American war film, the final film directed by Dorothy Arzner, one of the few female directors in Hollywood at the time.

Golden Gate Girls is a 2013 documentary film focusing on the life and works of Esther Eng (1914-1970), once honored as the first woman director of Southern China.  She crossed boundaries of both gender and culture by making Cantonese language films for Chinese audiences during and after WWII.  She was in fact the only woman directing feature-length films in America after Dorothy Arzner’s retirement in 1943 and before Ida Lupino began directing in 1949.  After her film career, she pioneered in establishing fine dining Chinese Restaurants in New York City.  She left her mark in both the Chinese and English press enabling director S. Louisa Wei to recover some of her lost stories.  Clips from her two extant films, stills from her eight other motion pictures, photos from her six albums, newsreels of San Francisco as she saw them, as well as hundreds of archival images are collected to present her life and work in the most stunning visuals.
