Alien invasion
The alien invasion or space invasion is a usual part of science fiction stories and film, in which extraterrestrials invade the Earth either to exterminate and supplant human life, enslave it under an intense state, harvest people for food, steal the planet's resources, or destroy the planet altogether. The invasion scenario has been used as an allegory for a protest against military hegemony and the societal ills of the time. H.G. Wells' novel "The War of the Worlds" extended the invasion literature that was already common when science fiction was first emerging as a genre. Prospects of invasion tended to vary with the state of current affairs, and current perceptions of threat.
History of science fiction films
The history of science fiction films parallels that of the motion picture industry as a whole, although it took several decades before the genre was taken seriously. Since the 1960s, major science fiction films have succeeded in pulling in large audience shares, and films of this genre have become a regular staple of the film industry. Science fiction films have led the way in special effects technology, and have also been used as a vehicle for social commentary. Science fiction films appeared very early in the silent film era. The initial attempts were short films of typically 1 to 2 minutes in duration, shot in black and white, but sometimes with colour tinting.
Science fiction film
Science fiction film (or sci-fi film) is a genre that uses speculative, fictional science-based depictions of phenomena that are not fully accepted by mainstream science, such as extraterrestrial lifeforms, alien worlds, extrasensory perception and time travel, along with futuristic elements such as spacecraft, robots, cyborgs, interstellar travel or other technologies. Science fiction films have often been used to focus on political or social issues, and to explore philosophical issues like the human condition. In many cases, tropes derived from written science fiction may be used by filmmakers ignorant of or at best indifferent to the standards of scientific plausibility and plot logic to which written science fiction is traditionally held.
Alien (film)
Alien is a 1979 science fiction horror film directed by Ridley Scott, and starring Sigourney Weaver, Tom Skerritt, Veronica Cartwright, Harry Dean Stanton, John Hurt, Ian Holm and Yaphet Kotto. It is the first movie in what became a large "Alien" franchise. The film's title refers to a highly aggressive extraterrestrial creature that stalks and attacks the crew of a spaceship. Dan O'Bannon, drawing upon previous works of science fiction and horror, wrote the screenplay from a story he co-authored with Ronald Shusett. The film was produced by Gordon Carroll, David Giler and Walter Hill through their company Brandywine Productions, and was distributed by 20th Century Fox.
Science fiction
Science fiction (often shortened to SF or sci-fi) is a genre of speculative fiction, typically dealing with imaginative concepts such as 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 avoids the supernatural, unlike the related genre of fantasy. Historically, science-fiction stories have had a grounding in actual science, but now this is only expected of hard science fiction.
U.S. television science fiction
U.S. television science fiction is a popular genre of television in the United States that has produced many of the best-known and most popular science fiction shows in the world. Most famous of all, and one of the most influential science-fiction series in history, is the iconic "" and its various spin-off shows, which comprise the Star Trek franchise. Other hugely influential programs have included the 1960s anthology series "The Twilight Zone," the internationally successful "The X-Files," and a wide variety of television movies and continuing series for more than half a century. The first popular science-fiction program on American television was the children's adventure serial "Captain Video and His Video Rangers", which ran from June 1949 to April 1955.
History of science fiction
The literary genre of science fiction is diverse, and its exact definition remains a contested question among both scholars and devotees. This lack of consensus is reflected in debates about the genre's history, particularly over determining its exact origins. There are two broad camps of thought, one that identifies the genre's roots in early fantastical works such as the Sumerian "Epic of Gilgamesh" (earliest Sumerian text versions c. 2150–2000 BCE). A second approach argues that science fiction only became possible sometime between the 17th and early 19th centuries, following the scientific revolution and major discoveries in astronomy, physics, and mathematics.
