The first of five books in the Hitchhiker’s Guide to the Galaxy comedy science fiction series by Douglas Adams was published 12th October 1979. Originally a radio comedy broadcast, it was later adapted to other formats, and over several years it gradually became an international multi-media phenomenon. Adaptations have included stage shows, a “trilogy” of five books, a sixth novel penned by Eoin Colfer, a 1981 TV series, a computer game, and three series of three-part comic book adaptations of the first three novels published by DC Comics between 1993 and 1996. A film version, produced and filmed in the UK, was released in April 2005, and radio adaptations of the third, fourth, and fifth novels were broadcast from 2004 to 2005. All versions, the series follows the adventures of Arthur Dent, a hapless Englishman, Ford Prefect, who named himself after the Ford Prefect car to blend in with what was assumed to be the dominant life form, automobiles, and is an alien from a small planet somewhere in the vicinity of Betelgeuse and a researcher for the eponymous guidebook; Zaphod Beeblebrox, Ford’s semi-cousin and the Galactic President; the depressed robot Marvin the Paranoid Android; and Trillian, formerly known as Tricia McMillan, a woman Arthur once met at a party in Islington and the only other human survivor of Earth’s destruction.
In the Hitchhiker’s Guide to the Galaxy, the characters visit the legendary planet Magrathea, home to the now-collapsed planet-building industry, and meet Slartibartfast, a planetary coastline designer who was responsible for the fjords of Norway. Through archival recordings, he relates the story of a race of hyper-intelligent pan-dimensional beings who built a computer named Deep Thought to calculate the Answer to the Ultimate Question of Life, the Universe, and Everything. When the answer was revealed to be 42, Deep Thought explained that the answer was incomprehensible because the beings didn’t know what they were asking. It went on to predict that another computer, more powerful than itself would be made to calculate the question for the answer. (Later on, referencing this, Adams would create the 42 Puzzle, a puzzle which could be approached in multiple ways, all yielding the answer 42.) The computer, was the Earth, and was destroyed by Vogons to make way for a hyperspatial express route, five minutes before the conclusion of its 10-million-year program. Two of a race of hyper-intelligent pan-dimensional beings who commissioned the Earth in the first place, disguised themselves as Trillian’s mice, and want to dissect Arthur’s brain to help reconstruct the question, since he was part of the Earth’s matrix moments before it was destroyed, and so he is likely to have part of the question buried in his brain.
In The Restaurant at the End of the Universe , Zaphod gets separated from the others and finds he is part of a conspiracy to uncover who really runs the Universe. He then meets Zarniwoop, editor for The Guide, who knows where to find the secret ruler and is briefly reunited with the others for a trip to Milliways, the restaurant of the title. Zaphod and Ford decide to steal a ship from there, which turns out to be a stunt ship pre-programmed to plunge into a star as a special effect in a stage show and are unable to change it’s course. Meanwhile Ford and Arthur, end up on a spacecraft full of the outcasts of the Golgafrinchan civilisation, which crashes on prehistoric Earth; leaving Ford and Arthur stranded, and it becomes clear that the inept Golgafrinchans are the ancestors of modern humans, having displaced the Earth’s indigenous hominids. Adams himself considered Restaurant to be his best novel of the five.
In Life, the Universe and Everything , Slartibartfast, enlists the aid of Ford, Arthur, Marvin, Zaphod and Trillian to prevent the people of the planet Krikkit from escaping their home planet, on which they have been imprisoned and causing a Galactic War which will wipe out all life in the Universe. In So Long, and Thanks for All the Fish, Arthur returns home to Earth, where He meets and falls in love with a girl named Fenchurch, and discovers this Earth is a replacement provided by the dolphins in their Save the Humans campaign. Eventually he rejoins Ford, who claims to have saved the Universe in order to hitch-hike one last time and see God’s Final Message to His Creation. Along the way, they are also joined by Marvin, the Paranoid Android, who, although 37 times older than the universe itself (what with time travel and all), has just enough power left in his failing body to read the message and feel better about it all before expiring.
Finally, in Mostly Harmless, Vogons take over The Hitchhiker’s Guide (under the name of InfiniDim Enterprises), to finish the task of obliterating the Earth. Arthur loses Fenchurch and travels around the galaxy despondently, before crashing his spaceship on the planet Lamuella, where he settles in happily as the official sandwich-maker for a small village of simple, peaceful people. Meanwhile, Ford Prefect breaks into The Guide’s offices, gets himself an infinite expense account from the computer system, and then meets The Hitchhiker’s Guide to the Galaxy, Mark II, an artificially intelligent, multi-dimensional guide with vast power and a hidden purpose. Trillian leaves her daughter, Random Frequent Flyer Dent with Arthur, but she then steals The Guide Mark II and uses it to get to Earth. Arthur, Ford, Trillian, and Tricia McMillan (Trillian in this alternate universe) give chase & follow her to a crowded club, where an anguished Random becomes startled by a noise and inadvertently fires her gun at Arthur. The shot misses Arthur and kills Agrajag. Soon afterwards, The Guide Mark II removes all possible Earths from probability, which is bad news for all the main characters, apart from Zaphod, who were all on Earth at the time.
Author Eoin Colfer (Artemis Fowl) wrote a sixth instalment entitled And Another Thing, which sees the characters awoken from virtual reality as death rays bear down on Earth before being picked up by Zaphod and joined by Bowerick Wowbagger, the Infinitely Prolonged. Zaphod then travels to Asgard to get Thor’s help, to deal with the Vogons, who are heading to the planet Nano in order to destroy a colony of people who also escaped Earth’s destruction. Meanwhile Arthur, Wowbagger, Trillian and Random head to Nano to try to stop the Vogons. During the journey Wowbagger and Trillian fall in love, then Zaphod arrives with Thor, who becomes the planet’s God. Wowbagger then marries Trillian and Thor manages to stop the first Vogon attack. Meanwhile, Constant Mown, son of Prostetnic Jeltz, convinces his father that the people on the planet are not citizens of Earth, but are citizens of Nano, which means that it would be illegal to kill them. Arthur then finds himself flung across alternate universes during a hyperspace jump but ends up exactly where he’d want to be And then the Vogons turn up again….
The popularity of the radio series gave rise to a six-episode television series, which first aired on BBC 2 in 1981. It employed many of the actors from the radio series and was based mainly on the radio versions of Fits the First through Sixth. A second series was also planned, although it was never made. On 21 June 2004, BBC Radio announced that a new series of Hitchhiker’s based on the third novel would be broadcast followed by a further series based on the fourth and fifth novels. A movie adaptation of The Hitchhiker’s Guide to the Galaxy was also released in 2005 starring Martin Freeman as Arthur, Mos Def as Ford, Sam Rockwell as Zaphod Beeblebrox and Zooey Deschanel as Trillian, with Alan Rickman providing the voice of Marvin the Paranoid Android (and Warwick Davis acting in Marvin’s costume), and Stephen Fry as the voice of the Guide/Narrator. The plot of the film adaptation of Hitchhiker’s Guide differs widely from that of the radio show, book and television series and visits to Vogsphere, the homeworld of the Vogons (which, in the books, was already abandoned), and Viltvodle VI are inserted. The film covers events in the first four radio episodes, and ends with the characters en route to Milliways, the Restaurant at the End of the Universe, leaving the opportunity for a sequel open.
