Peter Schønau Fog (born 20 April 1971) is a Danish film director.
 Fog's debut feature film, "Kunsten at græde i kor" (English: "The Art of Crying"), based on Erling Jepsen's novel of the same name, premiered 27 April 2007 and received critical acclaim.
 For the film, he received the Nordic Council Film Prize for Best Film of 2007 as well as the 2007 Robert Award for Best Danish Film and 2008 Bodil Award for Best Danish Film.
Romance (Romance X) is a 1999 French art house film written and directed by Catherine Breillat.
 It stars Caroline Ducey, pornographic actor Rocco Siffredi, Sagamore Stévenin and François Berléand.
 The film features explicit copulation scenes, especially one showing Caroline Ducey's coitus with Rocco Siffredi.
 "Romance" is one of several arthouse films featuring explicit, unsimulated sex, such as "The Brown Bunny" (2003), "9 Songs" (2004), "All About Anna" (2005), and "Shortbus" (2006).
Dog Days (German: Hundstage ) is a 2001 Austrian feature film directed by Ulrich Seidl.
 It is characterized by a disturbing naturalistic style which is a trademark of Seidl's directing.
 The film stars a mix of professional and amateur actors and it became mildly controversial for its depiction of unsimulated sex.
Sven Johan Methling (or Sven Methling Jr.) (1918–2005) was a Danish film director and screenwriter.
 The son of actor and film director Svend Methling, Methling Jr. was best known for a series of light-hearted comedies.
 His 1959 comedy "Vi er allesammen tossede" ("All of us are Crazy") received the Bodil Award for Best Danish Film.
 Methling also received the Bodil Award for Best Danish Film for the 1955 war drama "Der kom en dag" ("There Will Come a Day").
Unsimulated sex is the presentation in a film of sex scenes where the actors engage in an actual sex act, and are not just miming or simulating the actions.
 At one time in the United States such scenes were restricted by law and self-imposed industry standards such as the Motion Picture Production Code.
 Films showing explicit sexual activity were confined to privately distributed underground films, such as stag films or "porn loops".
 Beginning in the late 1960s, most notably with "Blue Movie" by Andy Warhol, mainstream cinemas began pushing boundaries in terms of what was presented on screen.
 Although the vast majority of sexual situations depicted in mainstream cinema are simulated (in early pornography, the main actors engaged in simulated sex, with inserts placed in the film), on rare occasions actors engage in real sex.
 The difference between these films and pornography is that, while such scenes might be considered erotic, the intent of these films is not solely pornographic.
All About Anna is a Danish film released in 2005, directed by Jessica Nilsson and starring Gry Bay and Mark Stevens.
 The film is explicit in its exploration of sexual relationships.
The Danish Film Database (Danish: "Filmdatabasen" , formerly Danish National Filmography, Danish: "Danmarks Nationalfilmografi") is a database maintained by the Danish Film Institute about Danish films since 1896 including silent films, short films, and documentary films.
 When it went online in November 2000, it included data on all 1,000 Danish films produced between 1968 and 2000, and 10,000 persons, which by 2014 had been expanded to 22,000 titles, 106,000 persons and 6,000 companies.
 A media gallery with photos, programmes, poster scans, and trailers is available.
 The database also includes information on premiere dates for foreign films in Danish cinemas since 2000.
Tree of Knowledge (Danish: Kundskabens træ ) is a 1981 Danish coming-of-age drama directed by Nils Malmros.
 The film details the lives of 17 teenage schoolmates in 1950s Denmark.
 Shooting on location at the high school which he had attended, Malmros took two years to film the action, so the cast members reflected the real life physical and emotional development of their characters.
 Film Critic Roger Ebert of the Chicago Sun-Times wrote ""The Tree of Knowledge" is the truest and most moving film I have ever seen about the experience of puberty... a creative act of memory about exactly what it was like to be 13 in 1953."
 Despite critical praise, "Tree of Knowledge" received only two awards: the Danish Film Critics Bodil Award for Jan Weincke's cinematography and the Audience Award at the Lübeck Nordic Film Festival.
 "Tree of Knowledge" is one of the top 100 Danish films listed by the Danish Film Institute and is one of ten films listed in the cultural canon of Denmark by the Danish Ministry of Culture.
L'Ange et la femme ("The Angel and the Woman") is a 1977 Quebecois fantasy romance film directed by Gilles Carle.
 The film follows a woman who, after being brutally shot, dies in the snow and is resurrected by an angel who falls in love with her and eventually teaches her how to incinerate objects with her mind.
 The film is shot entirely in black-and-white and gained some controversy due to its explicit unsimulated sex scenes between the two leads.
Caligula (Italian: "Caligola") is a 1979 Italian-American erotic historical drama film focusing on the rise and fall of the Roman Emperor Caligula.
 It stars Malcolm McDowell, Teresa Ann Savoy, Helen Mirren, Peter O'Toole, John Steiner and John Gielgud.
 It is the only feature film produced by the men's magazine "Penthouse".
 Producer Bob Guccione, the magazine's founder, intended to produce an explicit pornographic film with a feature film narrative and high production values.
 He also cast Penthouse Pets as extras in unsimulated sex scenes filmed during post-production by himself and Giancarlo Lui.
