A Clockwork Orange was published in 1962 by
Anthony Burgess. Interestingly, the book contained twenty-one chapters in its British debut, but only twenty chapters in its American release. Burgess was miffed about the decision by his New York publisher to "abridge" the book for its American audience, but he couldn't very well object at the time, as he was a starving writer. In any case, he got even eventually, when the book was re-released in 1986 in all of its twenty-one-chapter glory.
Unfortunately, Stanley Kubrick's movie bearing the same name was modeled after the slimmer American book release -- that is, the one without the final chapter. To Burgess's dismay, Kubrick's movie memorialized an incomplete version of his work. In any case, it turns out that Burgess actually didn't like his novel
A Clockwork Orange, anyway. (Burgess liked it as much as
Beethoven liked his
Minuet in G, or
Rachmaninoff his Prelude in C Sharp Minor, written when Rachmaninoff was a mere boy.)
