The Man I Love (1929 film): The Man I Love (1929) is a part-talking sound film from Paramount Pictures produced in parallel silent and sound versions.  This film survives in a copy sold to television in the 1950s.  The film stars Richard Arlen.  Some sources refer to this as Arlen's first sound film, but he co-starred Nancy Carroll in Dorothy Arzner's "Manhattan Cocktail" (1928), another part-talking picture released by Paramount.

Her collaboration with Claire Johnston on the work of Hollywood film director Dorothy Arzner provoked debate among feminist film scholars over the following decades.

Merrily We Go to Hell: 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 Hall (actress): Dorothy Hall (December 3, 1906 – February 2, 1953) was an American film actress in the late 1920s and early 1930s.  She began her career as an actress on Broadway and transitioned fully into film acting in the late 1920s.  She had small roles in films such as "The Winning Oar" (1927) and "The Broadway Drifter" (1927) and was later featured in the Vitaphone short "In the Nick of Time" (1929) and "The Laughing Lady" (1929).  Her final and best known film role was in Dorothy Arzner's "Working Girls" (1931) where she plays Mae Thorpe.  Dorothy Hall died on February 2, 1953 in New York City.

Dorothy Arzner: 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.

Ballet master: Ballet Master (also "Balletmaster", "Ballet Mistress" [increasingly archaic English language use], "Premier Maître de ballet" or "Premier Maître de ballet en Chef") is the term used for an employee of a ballet company who is responsible for the level of competence of the dancers in their company.  In modern times, ballet masters are generally charged with teaching the daily company ballet class and rehearsing the dancers for both new and established ballets in the company's repertoire.  The artistic director of a ballet company, whether a male or female, may also be called its ballet master.  Historic use of gender marking in job titles in ballet (and live theatre) is being supplanted by gender-neutral language job titles regardless of an employee's gender identity or expression (e.g. "Ballet Master" in lieu of "Ballet Mistress", "Wig Master" as an alternative to "Wig Mistress").
