Trivia: The Hitchhiker's Guide to the Galaxy
General franchise trivia:
- Accidentally Accurate: Adams didn't write jokes in Base 13, but the fact remains that using THAT numerical base, 6X9 is indeed 42.
- Adaptation Sequence: Radio Serial —> Books —> TV Series —> Adventure Game —> Movie
- Beam Me Up, Scotty!: Say it with me, people. It's "The Answer to the Ultimate Question of Life, the Universe and Everything". Not the meaning of life.
- Life Imitates Art: Smartphones and tablets with access to Wikipedia mimic the capability and functions of the Guide with uncanny accuracy.
- Recycled Script:
- Life, the Universe and Everything was based on an unused Doctor Who script, Doctor Who and the Krikketmen. It might have been a second Hitchhiker TV series.
- The later radio series were essentially adaptations of Adams' last three Hitchhiker novels, retconning pretty much the entire events of the second series to being merely the delusional rantings of Zaphod Beeblebrox, instead of following directly from them.
- Technology Marches On: Digital watches sure are a neat idea, huh? (In the later radio series, and the movie, they were replaced by mobile phones.)
- Trope Namer:
- Unfortunate Name: Slartibartfast. Adams wanted him to have an immense sadness, so gave him a terrible name. He started with FartyFuckBalls, and mutated it until it sounded rude without actually being rude.
- Author Existence Failure: Trope Namer, almost; the third book mentions a "total existence failure". Later, of course, succumbed to the trope when Adams died while working on the sixth book; his last published collection of pieces, The Salmon of Doubt, contains an early draft of a Dirk Gently novel that Adams was hoping to rework into a Hitchhiker book.
- Creator Breakdown: Regarding the Downer Ending of Mostly Harmless and the mixed-to-negative reaction from fans, Adams conceded, "I just had a thoroughly miserable year, and I was trying to write a book against that background." He intended a sixth book to give the series a better conclusion, but succumbed to Author Existence Failure first.
- Executive Meddling: In Life, the Universe, and Everything, the Silver Bail of Peace is the Rory Award for "Most Gratuitous Use of the Word 'Fuck' in a Serious Screenplay". US censors were offended, and Adams, bowing to their wishes, promptly changed the offending word to "Belgium". Fortunately, the resulting passage was much funnier, as Adams modified the surrounding conversation to fit the change, as well.
Arthur: "Have you ever been to Belgium in fact?"
- Author Existence Failure: Douglass Adams died a year before the film was completed, though after he'd finished his parts of the script.
- God Created Canon Foreigner: Many of the differences from previous versions were Adams creations, from pre-death versions of the script, including the POV Ray, the flyswatters, Humma Kavula, and the romantic elements.
- Hey, It's That Guy!:
- Hey, It's That Voice!:
- In Memoriam: "For Douglas."
- Retroactive Recognition: The four leads are Martin Freeman, Mos Def, Zooey Deschanel, and Sam Rockwell. We later see John Malkovich and Bill Nighy.
- Slartibartfast is not named for the majority of the episode he first appears in. Word of God explained that it was a joke at the expense of the woman who had to type the scripts - that she'd typed this name a dozen times and he simply said 'My name is not important'.
- The seventh episode was originally broadcast on 24 December 1978. Consideration was given, partly due to the date and partly due to the fact that all the plot threads had been tied off at the end of episode six, to making it a stand-alone Christmas special in which Marvin would have been both figuratively and literally the star (of Bethlehem), and by participating in a nativity scene would be cured of his depression. In the end they made it a normal episode, devoted to untying enough plot threads for the series to continue.
- Hey, It's That Voice!:
- In the original radio series, David Jason was the Golgafrincham "B" Ark Captain, and Jim Broadbent played one of the complaining philosophers and one of the gun-happy cops on Magrathea.
- In the recent radio adaptations we have Christian Slater as Wonko the Sane, Jackie Mason as The East River Creature and Stephen Fry (again) as Murray Bost Henson.
- Hipgnosis: Did the cover art for the British releases of the soundtrack albums.
- Real Song Theme Tune: The theme for the radio show was a snatch of the Eagles' "Journey Of The Sorceror", an instrumental from their 1975 album One Of These Nights. It would be re-orchestrated for the Radio L Ps, and that arrangement was later used for the TV series.
TV Show trivia:
- Hey, It's That Guy!:
- Peter Davison (who at the time was married to Sandra Dickinson) as a creature that wants you to eat it!
- And the Black Guardian was the voice of Deep Thought.
- Igor was Garkbit the Waiter.
- Darth Vader is Hotblack Desiato's bodyguard, and is responsible for his body. (David Prowse wore the Vader suit in Star Wars, but didn't do the voice.)
- Slartibartfast disapproves of the Beatles.
- P.R. Deltoid is the captain of the Golgafrincham B Ark, and the Decaying Master is one of his officers.
- Tim Stamper is Max Quordlepleen.
- Prop Recycling:
- The background characters in the restaurant at the end of the universe are equipped almost entirely with costumes recycled from earlier episodes, and in particular from the various Guide entries, thus helping justify the expense of items which otherwise would have appeared on screen for only a few seconds each.
- A badge from one of the Golgafrincham hats would be worn by Arnold Rimmer.
- Recycled Set: The Vogon spaceship interiors were from Alien.
- What Could Have Been: At one point a second series was planned which would've been based on the Doctor Who story which later formed the basis of Life, the Universe and Everything.
