Now then:
It occurred to me yesterday that if I were going to do Riverworld as a series, I would take on more (slightly more) of a Lost approach.
In the books, 35 billion human beings, everyone who ever lived between about 2 million BC and 2008 AD, wakes up naked, all at the same time, on the banks of the River. Everyone is hysterical and terrified, running around, freaking out.
I'd follow this exactly in the first episode. Introduce the main characters (Burton, Peter Frigate, the rest as detailed in the book, including the alien, Monat) and start revealing the secrets of the Riverworld, slowly - these people have no idea at first where they are and what happened to them or who's responsible. And yeah, you can easily get across the idea that everyone's naked with strategic camera angles.
That's just a brief synopsis to give you an idea - to me the real charm of the Riverworld novels was the incredible mystery of the place, confronted by a humanity which had been stripped of its technology, meaningful resources and even its clothes (at first), a humanity in the hands of beings about as powerful as the planet builders recently seen in Stargate Universe...and eventually overcoming all this to become masters of their fate.
A series could reveal new wonders, new cultures, and the heroes would slowly learn more about the Riverworld simply by getting out there, having a look around, and using their brains. Figuring out how to improvise and turn the situation to their advantage (like how the Riverboat used the grailstones to recharge)
And Burton would be the frakking hero, damn it.
I think it would be very doable if you didn't reveal all the mysteries at once and build the database as you went, so to speak. Plus the culture clashes were just plain interesting. The character combinations available would lead to some really funny or tragic plots. What happens when a 20th century American hooks up with a Jewish woman who knew Moses? Or a Roman soldier hooked up with a Victorian woman? What happens when you find your spouse and she's shacked up now with, say, Spartacus? That kind of stuff would be fun in itself.
Thoughts, opinions?
