In the radio, LP and television versions of the story, Arthur is played by Simon Jones (not to be confused with Peter Jones, the voice of the Guide). In Ken Campbell's stage production from 1979, Chris Langham took the part. In the film he is played by Martin Freeman. In The Illustrated Hitchhiker's Guide to the Galaxy, he is portrayed by Jonathan Lermit.
Along with Ford Prefect, Arthur Dent barely escapes the Earth's destruction as it is demolished to make way for a hyperspace bypass. Arthur spends the next several years, still wearing his dressing gown, helplessly launched from crisis to crisis while trying to straighten out his lifestyle. He rather enjoys tea, but seems to have trouble obtaining it in the far reaches of the galaxy. In time, he learns how to fly and carves a niche for himself as a sandwich-maker.
In most versions of the series, Arthur and Ford eventually find themselves back on Earth, but two million years in the past, marooned with a third of the Golgafrincham population (consisting of hairdressers, account executives, film makers, security guards, telephone sanitisers, and the like). The Golgafrincham arrival spurs the extinction of the native "cavemen" (although, as Ford Prefect pointed out, they did not live in caves, to which a witty repartee was that they 'might have been getting their caves redecorated'), resulting in the human race's eventual replacement by a shipload of middle managers, telephone sanitisers and hairdressers.
The original radio series and the television series end at this point, although a second radio series was made in which Ford and Arthur are rescued by Ford's cousin Zaphod Beeblebrox and have further adventures, and which ends with Arthur stealing Zaphod's spaceship, the Heart of Gold (which Zaphod had himself stolen) and striking out with only Marvin the Paranoid Android, Eddie the shipboard computer, a cloned archaeologist named Lintilla, a bunch of appliances with Genuine People Personalities, and a rather battered copy of the Hitchhiker's Guide to the Galaxy for companionship.
In the novels and the new[further explanation needed] radio series (the latter of which dismisses the events of the second radio series as one of Zaphod's "psychotic episodes"), Ford and Arthur escape prehistoric Earth via an eddy in the space-time continuum and a time-travelling Chesterfield sofa that deposits them in the middle of Lord's Cricket Ground at the climax of the final (in more ways than one, it turns out) match in the Ashes series, the day before the destruction of Earth by the Vogons. Having escaped the destruction of Earth once more and survived further adventures, Arthur eventually finds himself once more back on Earth (or rather an alternative Earth founded by the Dolphins to save the human race from extinction). Here he falls in love with a woman named Fenchurch and seems set to live happily ever after — at least until the following — and final — novel, Mostly Harmless. By the end of this fifth novel, Earth and all of its possible permutations and alternate versions are destroyed once and for all, and everybody dies, at least as far as the novel goes. However it is subtly hinted that Arthur, his friends, and a few Earths might have survived.
In the Quintessential Phase of the radio series, there are multiple alternative endings after the final destruction of all possible Earths. The final ending here consists of the Babel fish carried by Arthur, Trillian, Ford, and Random having a sense for self-preservation, i.e. at the last minute they teleport the person they are inhabiting, and anyone nearby (namely Tricia McMillan), to safety. They are teleported to Milliways where they meet up with Zaphod, both Trillians merge, leaving her with her British accent but her blonde-American hair. Marvin has been rebuilt as his warranty has yet to expire and is parking cars at Milliways again (he has been promoted, he remarks; he now has his own bucket). Finally, they meet up with Fenchurch again who was teleported to Milliways after we last saw her in the Quandary Phase and has been working as waitress there, waiting for Arthur. They all settle in together, leaving the series on an upbeat note and allowing for further adventures.
In the latest book, And Another Thing..., it is revealed that there are other Arthur Dents in the different dimensions of the book series, but they are all deceased, due to various mishaps of fate, so that only the Arthur who was rescued from Earth remains. One actually briefly appears in the book, wearing Arthur's traditional dressing gown and slippers, and is destroyed with the rest of Earth by the Grebulons. Ford almost sees him, but searches for a drink and misses him being vaporized.
Arthur dies in the fifth installment of the book series, Mostly Harmless, in a club called Beta (owned by Stavro Mueller) when the Earth and all its duplicates are seemingly destroyed by the Grebulons. Adams frequently expressed his disdain for this ending in retrospect, claiming that it was too depressing and came about as the result of him having a bad year.
In the radio series, Arthur is saved by the Babel Fish, which can teleport itself, along with its carrier, out of danger. Arthur and the others who died in the books are instead teleported by their Babel Fish to somewhere safer than Sector ZZ9 Plural Z Alpha. This is also used in Trillian's dream sequence, as the reason for their escape.
In And Another Thing..., written by Eoin Colfer, Arthur was put into a dream sequence (presumably referring to the epilogue of the radio series) and then frozen in time by the Guide Mk.2. The Guide's batteries soon run out, however, so all the main characters are re-awakened on the exploding Earth, at the exact point where Mostly Harmless left off. Zaphod then rescues them in the Heart of Gold. All alternative Arthurs are killed. In the end, Arthur Dent traveling in hyperspace on an interstellar passenger ship, looked to the seat next to him to find Fenchurch sitting there talking to him as Arthur himself vanishes out of existence.
In the 2005 Christmas special of Doctor Who, "The Christmas Invasion", the Tenth Doctor, played by David Tennant, after having just finished saving the world still dressed in night clothes and a dressing-gown, compares himself to Arthur Dent whom he describes as a "nice man" which quite possibly suggests that the Doctor has at some point been present in the same universe as the characters of the Hitchhiker's Guide. Incidentally, the Fourth Doctor in the episode "Destiny of the Daleks" was seen to be reading and criticising a book by Oolon Colluphid, a reference Douglas Adams apparently inserted himself while working as a script editor on the show.
The radio drama Adventures in Odyssey uses the character Arthur Dent in the Novacom Saga  who embodies the characteristics of outright ignoring, at first, the deception and weirdness that is occurring around him.
In the 4th episode of season 4 of Farscape, John Crichton, trapped in a far corner of the universe by a wormhole, compares himself to characters from Star Trek, characters from comics, Dorothy from The Wizard of Oz, and finally to Arthur Dent.
