Stanley Kubrick produced many masterpieces, but none as striking and gut-wrenching as A Clockwork Orange. The now immortal 1971 dystopian crime film adapted from Anthony Burgess's novel of the same name, it uses disturbing (for the time) imagery to make big statements about social, political, and economic issues.
Set in a dystopian near-future Britain, there's psychiatry, gang culture, juvenile delinquency and a healthy chunk of Beethoven in there as well. To this day, there is still no other film like it and it's standing in pop culture infamy will likely never change.
20. It Was Originally Called "The Ludovico Technique"
Despite the book being called A Clockwork Orange, Kubrick initially had the screenplay titled "The Ludovico Technique" after the seminal scene where Alex is subjected to aversion therapy.
In the end, he changed his mind and, with so many other elements of the screenplay exactly mirroring the book, it was decided that the title should as well. Just as well, really.
