Context: Gregory King Hoblit (born November 27, 1944) is an American film director, television director and television producer.

Douglas Sirk (born Hans Detlef Sierck; 26 April 1897 – 14 January 1987) was a German film director best known for his work in Hollywood melodramas of the 1950s. The woman's film is a film genre which includes women-centered narratives, female protagonists and is designed to appeal to a female audience.  Woman's films usually portray "women's concerns" such as problems revolving around domestic life, the family, motherhood, self-sacrifice, and romance.  These films were produced from the silent era through the 1950s and early 1960s, but were most popular in the 1930s and 1940s, reaching their zenith during World War II.  Although Hollywood continued to make films characterized by some of the elements of the traditional woman's film in the second half of the 20th century, the term itself disappeared in the 1960s.  The work of directors George Cukor, Douglas Sirk, Max Ophüls, and Josef von Sternberg has been associated with the woman's film genre.  Joan Crawford, Bette Davis, and Barbara Stanwyck were some of the genre's most prolific stars.
