Cinématon is a 199-hour-long experimental film by French director Gérard Courant.
 It was the longest film ever released until 2011.
 Composed over 28 years from 1978 until 2006, it consists of a series of over 2,987 silent vignettes (cinématons), each 3 minutes and 25 seconds long, of various celebrities, artists, journalists and friends of the director, each doing whatever they want for the allotted time.
 Subjects of the film include directors Barbet Schroeder, Nagisa Oshima, Volker Schlöndorff, Ken Loach, Benjamin Cuq, Youssef Chahine, Wim Wenders, Joseph Losey, Jean-Luc Godard, Samuel Fuller and Terry Gilliam, chess grandmaster Joël Lautier, and actors Roberto Benigni, Stéphane Audran, Julie Delpy and Lesley Chatterley.

Noboru Tanaka (田中登 , Tanaka Noboru , (August 15, 1937 – October 4, 2006)) was a Japanese film director known for his "Roman Porno" films, including three critically respected films known as the "Showa trilogy": "A Woman Called Sada Abe" ("aka" "Sada Abe: Docu-Drama") (1975), "Watcher in the Attic" (1976), and "" (1977), all three starring Nikkatsu "Roman porno" queen Junko Miyashita.
 The first film in this trilogy recounted the story of Sada Abe a year before Nagisa Oshima's internationally released "In the Realm of the Senses" (1976), which told the same story.
 Though at the time he was working, his career was overshadowed by directors such as Tatsumi Kumashiro and Chūsei Sone, many critics today judge Tanaka the best of Nikkatsu's "Roman porno" directors.
Arvid E. Gillstrom (13 August 1889 – 21 May 1935), was a Swedish film director and screenwriter.
 He was born "Arvid Evald Gyllström" in Annedal, Gothenburg, Sweden and died in Hollywood, California.
Império dos Sentidos (Portuguese for ""Realm of the Senses"") is the second studio album by the Brazilian musician Fausto Fawcett.
 Like "Fausto Fawcett e os Robôs Efêmeros", it was released by WEA (present-day Warner Music Group) in April 1989 and produced by Os Paralamas do Sucesso frontman Herbert Vianna, who also co-authored some tracks and played the electric guitar and keyboards.
 The album's title is a nod to the 1976 film "In the Realm of the Senses", directed by Nagisa Oshima; the title track uses samples from the film.
