A great example of what the world will be like after (and before too BTW) an astroid strike. Niven and Pournelle have written a classic novel, and well worth the time spent reading it.
You don't need to watch the movie......
I LOVE that book! Read it when it first came out, and still have an extremely battered copy. I take it out every once in awhile and re-read it.
Regards,
That book rocked. Impactor was a comet though.
