 The 15 parts were co-produced with television-companies of the Federal Republic of Germany (West-Germany at that time), Switzerland and France.
 As an additional 16th part for Germany a "Making Of" was produced under the title "Besuch bei den Besuchern" (Visiting the Visitors).
 In West-Germany the series got the title "Die Besucher" (The Visitors), in the German Democratic Republic and Australia it was called "Expedition Adam 84".

Bicentennial Man is a 1999 Canadian-American science fiction comedy-drama film starring Robin Williams, Sam Neill, Embeth Davidtz (in a dual role), Wendy Crewson, and Oliver Platt.
 Based on the novel "The Positronic Man" by Isaac Asimov and Robert Silverberg (which is itself based on Asimov's original novella of the same name), the plot explores issues of humanity, slavery, prejudice, maturity, intellectual freedom, conformity, sex, love, and mortality.
 The film, a co-production between Touchstone Pictures and Columbia Pictures, was directed by Chris Columbus.
 The title comes from the main character existing to the age of two hundred years, and Asimov's novella was published in the year the United States had its bicentennial.
James Clavell (10 October 1921 – 6 September 1994), born Charles Edmund Dumaresq Clavell, was an Australian-born British (later naturalized American) novelist, screenwriter, director, and World War II veteran and prisoner of war.
 Clavell is best known as a writer for his The Asian Saga series of novels and their televised adaptations.
 Clavell also authored screenplays, such as "The Great Escape" (1963) and "To Sir, with Love" (1967).
 Clavell wrote science fiction, as well, including an episode of the early sci-fi TV series 'Men Into Space' in 1959, titled 'First Woman on the Moon,' as well as the film script for the original (1958) version of the sci-fi/horror classic "The Fly", starring Vincent Price.
Doctor Who: Legacy is a match-3 puzzle RPG video game released on 27 November 2013 based upon the BBC television programme.

 The game launched focusing on the 11th Doctor (as played by Matt Smith), then later shifted the focus to the 12th Doctor (played by Peter Capaldi), upon his debut in the show.
 New characters and content are added to the game regularly upon them being "signed off" with both the actors and the BBC brand team.
 The game includes every incarnation of the Doctor from the television series (including the War Doctor) and well over 200 companions from both Classic and Modern Doctor Who.
 The game also closely followed Series 8 and 9 of the show with new levels launching each weekend alongside each episode and included new characters, costumes, and enemies from most of the episodes.
