Science fiction

Science fiction is a genre of speculative fiction dealing with imaginative concepts such as futuristic settings, futuristic science and technology, space travel, time travel, faster than light travel, parallel universes and extraterrestrial life. Science fiction often explores the potential consequences of scientific and other innovations, and has been called a "literature of ideas." It usually eschews the supernatural, and unlike the related genre of fantasy, historically science fiction stories were intended to have at least a faint grounding in science-based fact or theory at the time the story was created, but this connection has become tenuous or non-existent in much of science fiction.

Definitions

Science fiction is difficult to define, as it includes a wide range of subgenres and themes. Author and editor Damon Knight summed up the difficulty, saying "science fiction is what we point to when we say it", a definition echoed by author Mark C. Glassy, who argues that the definition of science fiction is like the definition of pornography: you do not know what it is, but you know it when you see it.

Doctor Who

Doctor Who is a British science-fiction television programme produced by the BBC from 1963 to the present day. The programme depicts the adventures of the Doctor, a Time Lord—a space and time-travelling humanoid alien. He explores the universe in his TARDIS, a sentient time-travelling space ship. Its exterior appears as a blue British police box, which was a common sight in Britain in 1963 when the series first aired. Accompanied by companions, the Doctor combats a variety of foes, while working to save civilisations and help people in need.

The show is a significant part of British popular culture, and elsewhere it has become a cult television favourite. The show has influenced generations of British television professionals, many of whom grew up watching the series. The programme originally ran from 1963 to 1989. There was an unsuccessful attempt to revive regular production in 1996 with a backdoor pilot, in the form of a television film. The programme was relaunched in 2005 by Russell T Davies, who was showrunner and head writer for the first five years of its revival, produced in-house by BBC Wales in Cardiff. The first series of the 21st century featured Christopher Eccleston in the title role and was produced by the BBC. Series two and three had some development money contributed by the Canadian Broadcasting Corporation (CBC), which was credited as a co-producer.Doctor Who also spawned spin-offs in multiple media, including Torchwood (2006–2011) and The Sarah Jane Adventures (2007–2011), both created by Russell T Davies; K-9 (2009–2010); and a single pilot episode of K-9 and Company (1981). There also have been many spoofs and cultural references to the character in other media.

Darth Vader

Darth Vader, also known as Anakin Skywalker, is a fictional character in the Star Wars universe. Vader appears in the original trilogy as the primary antagonist, while his past as Anakin Skywalker is central to the plot of the prequel trilogy.

The character was created by George Lucas and has been portrayed by numerous actors. His appearances span the first six Star Wars films, and his character is heavily referenced in Star Wars: The Force Awakens. He is also an important character in the Star Wars expanded universe of television series, video games, novels, literature and comic books. Originally a Jedi prophesied to bring balance to the Force, he falls to the dark side of the Force and serves the evil Galactic Empire at the right hand of his Sith master, Emperor Palpatine (also known as Darth Sidious). He is also the father of Luke Skywalker and Princess Leia Organa, grandfather of Kylo Ren, and secret husband of Padmé Amidala.

The American Film Institute listed him as the third greatest movie villain in cinema history on 100 Years... 100 Heroes and Villains, behind Hannibal Lecter and Norman Bates.

Star Wars

Star Wars is an American epic space opera franchise, centered on a film series created by George Lucas. It depicts the adventures of various characters "a long time ago in a galaxy far, far away".

The first film in the series, Star Wars (later subtitled Episode IV: A New Hope), was released on May 25, 1977 by 20th Century Fox and became a worldwide pop culture phenomenon. It was followed by the similarly successful sequels The Empire Strikes Back (1980) and Return of the Jedi (1983); these three films constitute the original Star Wars trilogy. A prequel trilogy was later released between 1999 and 2005, which received a more mixed reaction from critics and fans, compared to the original trilogy. All seven films were nominated for or won Academy Awards, and were commercial successes, with a combined box office revenue of $4.38 billion, making Star Wars the fourth highest-grossing film series. The series has spawned an extensive media franchise—the Star Wars expanded universe—including books, television series, computer and video games, and comic books, resulting in significant development of the series's fictional universe. Star Wars also holds a Guinness World Records title for the "Most successful film merchandising franchise." In 2012, the total value of the Star Wars franchise was estimated at USD $30.7 billion, including box-office receipts as well as profits from their video games and DVD sales.
