The Mice (who are actually pan-dimensional hyperbeings) who created the Computer (Deep Thought, which caluclated the Answer to be 42) that created the blueprints for an even bigger computer (Earth, that was to calculate the question to which the answer was 42, and was mere minutes away from it's scheduled completion before it's unfortunate demise), which was created by a race of people who's business was creating planets (the Magratheans).
Yeah, I just read through the Trilogy of 5. Again.
On to the Salmon of Doubt once more.
The movie wasn't all bad, I mean the actors were perfect for the roles, but the screenplay got really warped.
And really, the unfinished bit of Narrative in Salmon is a Dirk Gentley novel... though the end of Mostly Harmless really, really, makes me wish that he had written another one, and he did express his intent to write another novel before the end.
Mostly Harmless was meh though, no Marvin....
And everyone knows that Marvin the Paranoid Android is the greatest. Ever.
