BTW, that was a book I was required to read in public high school English classs in the 70's. (I still haven't forgiven that ugly, dope-smoking, long-haired hippy of a teacher for assigning that worthless book.) You see, this culture war has been going on for quite some time.
It wasn't required reading for me - I bought it after seeing the movie. I really fell in love with Rossini because of that film (all of the fight scenes were to the overture from La Gaza Ladra)
The last thing Burgess ever did was the screen play for a bizarre paleolithic film called In Search Of Fire. Featuring filfthy Neanderthals, canibalism, cave bear attacks, lots of sex with fat painted chicks, and four or so different invented prehistoric languages that made Aramaic and Latin sound downright friendly. It was a mess...
No wonder Zeffirelli is proud to have had him as the writer of the screen play...
On the other hand, I did rather like Jesus of Nazerath, as well as Romeo and Juliet - all of which reminds me how far we have slid in the last 30 years of this culture war.
