Context: Nymphomaniac (stylised onscreen and in advertising as NYMPH()MANIAC) is a 2013 European two-part art film written and directed by Lars von Trier.  The film stars Charlotte Gainsbourg, Stellan Skarsgård, Stacy Martin, Shia LaBeouf, Christian Slater, Jamie Bell, Uma Thurman, Willem Dafoe and Connie Nielsen.  The film was originally supposed to be only one complete entry; but, because of its multiple hour length, von Trier made the decision to split the project into two separate films.  "Nymphomaniac" was an international co-production of Denmark, Belgium, France, and Germany. Charlotte Lucy Gainsbourg (born 21 July 1971) is a British-French actress and singer.  She is the daughter of English actress Jane Birkin and French singer and songwriter Serge Gainsbourg.  After making her musical debut with her father on the song "Lemon Incest" at the age of 12, she released an album with her father at the age of 15.  More than 20 years passed before she released three albums as an adult ("", "IRM" and "Stage Whisper") to commercial and critical success.  Gainsbourg has also appeared in many films, including several directed by Lars von Trier, and has received both a César Award and the Cannes Film Festival Best Actress Award. Dimension is a short film written and directed by Lars von Trier, released in 2010.  The film was shot from 1991 to 1997.  The original intention was to continue production in three-minute segments every year for a period of 33 years for a final release in 2024.  However, von Trier lost interest in the project and it was shelved.  The short film consists of the completed footage at the time the film was abandoned. Pernille Fischer Christensen (born 24 December 1969) is a Danish film director and the older sister of actor Stine Fischer Christensen.  She started out in the movie business when she was 20 years old as an assistant to Tómas Gislason.  During that time, Gislason was closely connected to Lars von Trier, and she got to listen to Gislason and von Trier's discussions about movies.  In 1993, she went to The European Film College where she met and collaborated with Nanna Arnfred.  In 1999, she graduated from the National Film School of Denmark with the movie "India", which later went on to win the Cinéfondations 3rd Prize at the Film festival in Cannes.  After finishing film school she made a short film called "Habibti My Love", which won a Robert in 2003 for "best short subject". The Idiots (Danish: Idioterne ) is a 1998 Danish comedy-drama film written and directed by Lars von Trier.  It is his first film made in compliance with the Dogme 95 Manifesto, and is also known as Dogme #2.  It is the second film in von Trier's "Golden Heart Trilogy", preceded by "Breaking the Waves" (1996) and succeeded by "Dancer in the Dark" (2000).  It is among the first films to be shot entirely with digital cameras. Breaking the Waves is a 1996 film directed by Lars von Trier and starring Emily Watson.  Set in the Scottish Highlands in the early 1970s, it is about an unusual young woman, Bess McNeill, and of the love she has for Jan, her husband, who asks her to have sex with other men when he becomes immobilized from a work accident.  The film is an international co-production led by Lars von Trier's Danish company Zentropa.  It is the first film in Trier's Golden Heart Trilogy which also includes "The Idiots" (1998) and "Dancer in the Dark" (2000). Zentropa or Zentropa Entertainments is a Danish film company started in 1992 by director Lars von Trier and producer Peter Aalbæk Jensen.  Zentropa is named from the train company Zentropa in the film "Europa" (1991), which started the collaboration between Lars von Trier and Peter Aalbæk Jensen. The Five Obstructions is a 2003 Danish documentary film directed by Lars von Trier and Jørgen Leth.  The film is conceived as a documentary, but incorporates lengthy sections of experimental films produced by the filmmakers.  The premise is that von Trier has created a challenge for his friend and mentor, Jørgen Leth, another renowned filmmaker.  von Trier's favorite film is Leth's "The Perfect Human" (1967), and von Trier gives Leth the task of remaking "The Perfect Human" five times, each time with a different "obstruction" (or obstacle) imposed by von Trier. The Kingdom (Danish title: Riget) is an eight-episode Danish television mini-series, created by Lars von Trier in 1994, and co-directed by Lars von Trier and Morten Arnfred.
