The Hitchhiker's Guide to the Galaxy Primary and Secondary Phases

It introduced unfamiliar music,[1] mind-stretching concepts and the newest science mixed together with-out of-context parodies, unfeasibly rude names, "semantic and philosophical jokes",[1] compressed prose, and "groundbreaking deployment of sound effects and voice techniques".

This race of pan-dimensional beings had constructed a great computer, called Deep Thought, to answer the Ultimate Question of Life, the Universe and Everything.

The mice believe that as last-generation products of the computer matrix, Arthur and Trillian should be in an ideal position to find out the Question, and offer to make them "extremely rich" if they can do so.

The spaceship to which Ford and Arthur have teleported, marked as "Golgafrincham Ark Fleet, Ship B" is filled with bodies, such as frozen telephone sanitisers, hairdressers, and advertising account executives.

Reports to the Committee include an update on the development of the wheel (it is unclear what colour it should be), and a documentary about the native cave-men of the planet, who have started to die out since the arrival of the Golgafrinchams.

They decide to use the same technique (of choosing scrabble letters) randomly to find out what the question in Arthur's brainwave patterns is, although it might be wrong anyway.

Her fate is addressed in Fit the Seventh, that she had effected an escape but had then been forcibly married to the President of the Algolian chapter of the Galactic Rotary Club.

Cast The episode opens with Zaphod and Roosta in the Guide building, which is being towed to the Frogstar, "the most totally evil place in the Galaxy".

The guide has an entry that begins, 'Consider how lucky you are that life has been good to you so far...' However, it becomes apparent that the boulder they are under is actually the ship, the Heart of Gold, and Zaphod Beeblebrox comes out of it, rather the worse for wear.

Meanwhile, Prostetnic Vogon Jeltz confirms the identity of the ship and its occupants, then proceeds to wipe out half his crew in a fit of rage.

Jeltz is asked to hold off on his final destruction of the Heart of Gold until Halfrunt can make an arrangement for fees still owed by Zaphod.

As the episode ends, Eddie has been restored to normal function, and engages the IID, getting the ship out of firing range of the Vogons in the nick of time.

Cast The episode opens with more background material on Arthur Dent, specifically how the "remarkably unremarkable" human from Earth had an effect on the war between the G'Gugvunts and Vl'Hurgs, and will now have further significance on the planet Brontitall, where the Heart of Gold has just arrived.

Eddie calculates after they, and Arthur and Marvin, have departed the ship, that they are thirteen miles above ground level, despite there not being any mountains on the planet.

The bird reveals that the "cave" is actually a mile long marble sculpture of a plastic cup, hanging in the sky, part of a larger statue.

On the surface, Arthur encounters a Footwarrior, who has declared the planet of Brontitall to be the property of the Dolmansaxlil Galactic Shoe Corporation.

Lintilla, Arthur and Marvin continue their escape, while Ford and Zaphod finally arrive at a large, very old building, and enter it to take shelter from the still angry bird people.

Cast Ford and Zaphod have discovered a derelict spaceport, including one ship, still intact, with its supply lines still connected, and still having power.

While Arthur does this, Poodoo is explaining how keen he is to introduce the Allitnils to the Lintillas, for a quiet social evening, and "a priest [is] on hand in case anybody wants to get married at all.

At this point, we go back to Ford and Zaphod entering the very late space ship, just as the passengers are being woken from suspended animation for coffee and biscuits.

The autopilot argues with them over the statistical likelihood of another civilisation delivering the lemon soaked paper napkins required by the spaceship before it can depart, and Ford and Zaphod flee again, this time to the First Class compartment.

As they finally exit the Dolmansaxlil building, they set out for the same spaceport that Ford and Zaphod are in, but then discover that the suspended cup is heading towards the surface, with the Heart of Gold still inside.

Zaphod succeeds in his task, bringing the Heart of Gold - its improbability drive being necessary to reach the realm of the real ruler of the galaxy - to Zarniwoop's hiding place.

After the narrator describes who might be ruling the universe, we hear the voice of an old man attempting to feed his cat a bit of fish.

Zarniwoop attempts further questions, but is eventually brushed off, and it's discovered that Arthur has made away with the Heart of Gold, with Lintilla and Marvin aboard.

This leaves Ford, Zaphod and Zarniwoop stranded on the "Old Man in the Shack"'s planet, and here the episode ends - though open-ended with a spoken possibility of another series.

Brett departed the BBC after the pilot episode was recorded, and so casting suggestions and decisions were made by Adams and Geoffrey Perkins for the remainder of both series.

[12] Perkins also describes the casting of Simon Jones, Geoffrey McGivern, Jo Kendall, Bill Wallis and many others throughout the book containing the original radio series scripts.
