Here are a couple interesting factoids from A Clockwork Orange
> The actor who played Alex (Malcolm McDowell) can to this day still not go to an opticians because of the mental scarring the 'eye scene' caused him.
> The significance of the movie's title is that it is something mechanical inside of something organic, much like Alex after his "treatment."
> The writer's physical therapist, Julian, is played by David Prowse, who in Star Wars is the body of Darth Vader.
