Okay, so I read the book AFTER I saw the movie, but one gave me a greater appreciation for the other, so I highly recommend both. As for the movie, Denzel Washington and Julia Roberts are paired so beautifully and convincingly as reporter and law student respectively that their mutual respect for one another adds tremendous dramatic tension to this already fast-paced drama. And now that our planet is in peril the story line itself becomes an additional element of the life-or-death crisis.
