 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.

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.
