10 Things You Didn't Know About A Nightmare On Elm Street

And of course, for Freddy's iconic jumper, influence was taken from a homeless man that terrified Craven by staring through his bedroom window when he was 10 years old. And also Plastic Man from DC. Yes.

Freddy's jumper isn't just your average knitwear though, as whilst a vague childhood memory might have served as the starting point for Krueger's distinctive look, it certainly wasn't where Craven finished. There's a particular reason why the director decided to combine green and red as the colourway for his slasher villain - and surprisingly, it's got nothing to do with the holiday season, no matter how scary Christmas eve shopping centers might get.

In fact, the jumper is one of the few aspects of the character to be born from actual science rather than base emotional conjecture, coming to life when Craven read Scientific American and found that the human eye is rendered uncomfortable by specific shades of red and green in close proximity to each other. Apparently, our bodies struggle to recognise them when they're particularly snug, so Craven went right on ahead and slapped them on Freddy's outerwear for an extra layer of unpleasantness onto a creation that already boasts literal child murder. No such thing as overkill, eh?
