There are loads of Clockwork Orange trivia
here. The most amazing to me was that Anthony Burgess only received $500 for the film rights. Sheesh. It is currently voted as one of the top 100 films on imdb (#72).
Here's a bit of trivia you won't find -- my dad bought (or most likely traded for) a cabin-cruiser about the same time that the film came out. It was a godawful shade of orange. Yep... he let me christen her "The Clockwork Orange." I'll bet there were not many boats with the same name. It was wishful thinking though... that boat did not run like clockwork.
