The book that I would like to see made into a movie is Oryx and Crake, by Margaret Atwood. It is a tale set in a future that has allowed genetic engineering to go on uncontrolled, believing that mankind's continued survival would be ensured by manipulation of the genes of all living things, including humans.

The narrator of the tale is a character called Snowman, now. In the past, he had a normal name, Jimmy. But nothing is normal anymore. Snowman/Jimmy takes us back decades before, trying to figure out how things went wrong so quickly, as he mourns the loss of his lovely and beloved Oryx, and his best friend Crake. Snowman now lives in a world where he is the only being alive that would be recognized by us as human. The other sentient beings would immediately be seen as disconcertingly odd and other. They, the Children of Crake, have no knowledge of what came before them, except for what Snowman tells them. And what he tells them is not all truth.

It is a world come to grief, in an outlandish, yet wholly believable realm.

I won't reveal anymore, I prefer people to read it themselves and get the story as it has been superbly told by such a master of the art as Margaret Atwood.

I would like to see Brad Pitt, (who wouldn't) as the younger Snowman, then known as Jimmy, second choice would be Keifer Sutherland. The elder, Snowman, I think would be tailor made for Christopher Walken. I believe Crake would be best invoked by Jake Gyllenhaal. Oryx could be be played Marissa Tomei or Catherine Zeta-Jones. I'll leave the other minor characters up to ohers.
