I watched this movie last night after reading the book many moons ago.  Even though it was made in the '60s and is purely fiction, I was moved to the point of tears watching them burn books.  I think that it was so moving because the movie so graphically showed what happens under socialism.  The obvious jabs at the egalitarian movement of the socialist left are amazing for their prophetic overtones.  If you pay particular attention to the "Family" (the TV show) you'll notice that the female "cousin" gave a diatribe about "tolerance" in a segment that immediately preceeded Montague's reading an excerpt from a novel.  The intolerance shown by the guests at the party towards him for reading immediately after the "Family" told them that they should accept people for their differences is symbolic of the hypocritical "tolerance" campaigns of the leftists.  The are many, many more symbolic messages in the film and book that require more than one reading or viewing to fully appreciate.  Everybody here (especially our literates [Eric]) should read the book and watch the movie.

It's truly terrifying, as well as morbidly enthralling, that the British authors and moviemakers so accurately predicted the future of their (and from the appearance of things, our) nation.  

I read the book when I was in school. I have not seen the movie. Is it close to the book ? Does it end the same way ?

I haven't read the book in a long time.  The movie ends with Montague going to live with the Book People.  I believe that's how the book ends too, but since I haven't been able to find my copy of the novel I'm just guessing.

That in addition to George Orwell's Animal Farm and 1984, Ayn Rand's Anthem, Fountainhead, and Atlas Shrugged and Kurt Vonnegut's Welcome to the Monkey House should all be required reading.
