Parallel universe (fiction) in the context of "Fantasy world"

Star Trek is a 2009 American science fiction action film directed by J. J. Abrams, and written by Roberto Orci and Alex Kurtzman. It is the 11th film in the Star Trek franchise, and is also a reboot that features the main characters of the original Star Trek television series portrayed by a new cast, as the first in the rebooted film series. The film follows James T. Kirk (Chris Pine) and Spock (Zachary Quinto) aboard the USS Enterprise as they combat Nero (Eric Bana), a Romulan from their future who threatens the United Federation of Planets. The story takes place in an alternate reality that features both an alternate birth location for James T. Kirk and further alterations in history stemming from the time travel of both Nero and the original series Spock (Leonard Nimoy). The alternate reality was created in an attempt to free the film and the franchise from established continuity constraints while simultaneously preserving original story elements.

The idea for a prequel film which would follow the Star Trek characters during their time in Starfleet Academy was first discussed by series creator Gene Roddenberry in 1968. The concept resurfaced in the late 1980s, when it was postulated by Harve Bennett as a possible plotline for what would become Star Trek VI: The Undiscovered Country, but it was rejected in favor of other projects by Roddenberry. Following the critical and commercial failure of Star Trek: Nemesis and the cancellation of Star Trek: Enterprise, the franchise's executive producer Rick Berman and screenwriter Erik Jendresen wrote an unproduced film titled Star Trek: The Beginning, which would take place after Enterprise. After the separation of Viacom and CBS Corporation in 2005, former Paramount Pictures president Gail Berman convinced CBS to allow Paramount to produce a new film in the franchise. Orci and Kurtzman were soon approached to write the film, and Abrams was approached to direct it. Kurtzman and Orci used inspiration from novels and graduate school dissertations, as well as the series itself. Principal photography occurred between November 2007 and March 2008, in locations around California and Utah. Abrams wanted to avoid using greenscreen, and preferred sets and locations instead. Heavy secrecy surrounded the film's production and was under the fake working title Corporate Headquarters. Industrial Light & Magic used digital ships for the film, as opposed to miniatures used in most of the previous films in the franchise. Production for the film concluded by the end of 2008.

The evil twin is an antagonist found in many different fictional genres. The twin is physically nearly identical to the protagonist, but with a radically inverted morality. In films, they may have a symbolic physical difference from the protagonist—such as a goatee, eyepatch, scar, distinctive clothing, or a more muscular build—which makes it easy for the audience to visually identify the two characters. Sometimes, however, the physical differences between the characters will be minimized, so as to confuse the audience. Both roles are almost always played by either the same actor or the actor's actual twin (if the actor has one).

Though there may be moral disparity between actual biological twins, the term is more often used figuratively: the two look-alikes are not actually twins, but physical duplicates produced by other phenomena (e.g. alternate universes). In other cases, the so-called "evil" twin is a dual opposite to their "good" counterpart, possessing at least some commonality with the value system of the protagonist.

His Dark Materials is a trilogy of fantasy novels by Philip Pullman consisting of Northern Lights (1995; published as The Golden Compass in North America), The Subtle Knife (1997), and The Amber Spyglass (2000). It follows the coming of age of two children, Lyra Belacqua and Will Parry, as they wander through a series of parallel universes. The novels have won a number of awards, including the Carnegie Medal in 1995 for Northern Lights and the 2001 Whitbread Book of the Year for The Amber Spyglass. In 2003, the trilogy was ranked third on the BBC's The Big Read poll.

Although His Dark Materials has been marketed as young adult fiction, and the central characters are children, Pullman wrote with no target audience in mind. The fantasy elements include witches and armoured polar bears; the trilogy also alludes to concepts from physics, philosophy, and theology. It functions in part as a retelling and inversion of John Milton's epic Paradise Lost, with Pullman commending humanity for what Milton saw as its most tragic failing, original sin. The trilogy has attracted controversy for its criticism of religion. By 2024, more than 22 million copies of the novels had been sold in 50 countries, and they had been translated into 40 languages.

Philip Kindred Dick (December 16, 1928 – March 2, 1982) was an American science fiction short story writer and novelist. He wrote 45 novels and about 121 short stories, most of which appeared in science fiction magazines. His fiction explored varied philosophical and social questions such as the nature of reality, perception, human nature, and identity, and commonly featured characters struggling against alternate realities, illusory environments, monopolistic corporations, drug abuse, authoritarian governments, and altered states of consciousness. He is considered one of the most important figures in 20th-century science fiction.

Born in Chicago, Dick moved to the San Francisco Bay Area with his family at a young age. He began publishing science fiction stories in 1952, at age 23. He found little commercial success until his alternative history novel The Man in the High Castle (1962) earned him acclaim, including a Hugo Award for Best Novel, when he was 33. He followed with science fiction novels such as Do Androids Dream of Electric Sheep? (1968) and Ubik (1969). His 1974 novel Flow My Tears, the Policeman Said won the John W. Campbell Memorial Award for Best Science Fiction Novel.
