Social guidance films constitute a genre of educational films attempting to guide children and adults to behave in certain ways.  Originally produced by the U.S. government as "attitude-building films" during World War II, the genre grew to be a common source of instruction in elementary and high school classrooms in the United States from the late 1940s to the early 1970s.  The films covered topics including courtesy, grammar, social etiquette and dating, personal hygiene and grooming, health and fitness, civic and moral responsibility, sexuality, child safety, national loyalty, racial and social prejudice, juvenile delinquency, drug use, and driver safety; the genre also includes films for adults, covering topics such as marriage, business etiquette, general safety, home economics, career counseling and how to balance budgets. The 48 Hour Film Project is a contest in which teams of filmmakers are assigned a genre, a character, a prop, and a line of dialogue, and have 48 hours to create a short film containing those elements.  Shortly after the 48 hours of filmmaking, the films from each city are then screened at a theater in that city.  The Project was inspired by The 24 Hour Plays.  It has existed since 2001.  It was created by Mark Ruppert and is produced by Ruppert and Liz Langston.  In 2009, nearly 40,000 filmmakers made around 3000 films in 76 cities worldwide. A social problem film is a narrative film that integrates a larger social conflict into the individual conflict between its characters.  Like many film genres, the exact definition is often in the eye of the beholder, but Hollywood did produce and market a number of topical films in the 1930s and by the 1940s, the term "social problem" or "message" film was conventional in its usage among the film industry and the public.  Many characteristics that have grown to define the social problem film revolve around the perceived consciousness of the nation about a certain social issue and integrating that issue into a narrative structure.  Social problems such as the horrors of war, suffering of the poor, addiction, the rights of women, and the inhumanity of a certain world are often put on display.  The problem with defining this type of film as a genre lies within the ability it has to separate itself from films that display similar style, as a lot of films do address social issues.  However, the social problem film differentiates itself by focusing on the problems within the historical context of the current time, dealing with the social issue of a certain era as it applies to that era with a style that is much more didactic than its contemporaries.  Furthermore, the social problem film allows further immersion into a certain issue than other genre films.  For instance, gangster and prison films will reflect certain features of a social issue but won't actually fully explore the problem in the way that would qualify it for this genre. Project Grizzly is a 1996 National Film Board of Canada documentary about the lifelong project of Troy Hurtubise, a man who has been obsessed with researching the Canadian grizzly bear up close, ever since surviving an early encounter with such a bear. War film is a film genre concerned with warfare, typically about naval, air, or land battles, with combat scenes central to the drama.  It has been strongly associated with the 20th century.  The fateful nature of battle scenes means that war films often end with them.  Themes explored include combat, survival and escape, sacrifice, the futility and inhumanity of battle, the effects of war on society, and the moral and human issues raised by war.  War films are often categorized by their milieu, such as the Korean War; the most popular subject is the Second World War.  The stories told may be fiction, historical drama, or biographical.  Critics have noted similarities between the Western and the war film. Peter Lynch is a Canadian filmmaker, the director and writer of "Project Grizzly" and "Cyberman".

Audiences worldwide have responded to his work both critically and popularly." 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.
