The first film version of Anthony Burgess' classic 1962 novel A Clockwork Orange is not Stanley Kubrick's celebrated 1971 film of the same name, but a 70-minute art film by no less a person than Andy Warhol. Andy may have had talent in his pop art, but his direction in Vinyl leaves something to be desired.
I just read Burgess' novel for the first time this weekend, and unless people in 1965 had read it first, they might have had considerable difficulty trying to decipher just what in God's name is going on on-screen. The camera stays in one place for the whole movie, which adds to the feeling you're watching a high school play. Indeed, our protagonist reads out his lines with the monotony and lack of emotion you'd expect from high school actors. The film includes a couple things from the book not in Kubrick's version- the protagonist tearing up the books of a victim, a speech about how no one asks why a good person does good things. But in removing the Nadsat, Warhol in effect guts the story of its poetry.
The dancing to music goes on too long, and the protagonist describing what he sees in the conditioning films gets repetitive fast. Although I'll admit, I laughed good when they finally mixed it up with something truly bizarre- "I see little children having their teeth pulled out by yellow dwarfs." Wait, what? At the end of the day, it's Kubrick's version that does the most justice to its source material, and that's the reason it's the most remembered version.
