My post on Good Reads-
Anything by Don DeLillo is worth a look, and COSMOPOLIS is certainly no exception. The story is a kind of detached observation of 'a day in the life' of Eric Packer, a billionaire hedge-fund manager. He is in his stretch limousine, and he and his security staff are attempting to get across Manhattan to get Eric a haircut. Various employees, friends, and even his wife, visit him in the confines of his imperial office suite on wheels as he and his team battle traffic snarls, numerous riots, and odd political/cultural disturbances to make it to his favorite barber. I guess the main theme of the novel is that Parker has been betting against the rise of a particular currency, and, in the process, has lost all of his fortune which leads to his personal downfall.
It's a fairly interesting read, and the novel is relatively short, but David Cronenberg's film is much better because the action of the story works much better 'seen' rather than merely 'described'.
