By Craven's account, his own adolescent experiences led him to the name "Freddy Krueger"; he had been bullied at school by a child named Fred Krueger. Craven had done the same thing in his film "The Last House on the Left" (1972), where the villain's name was shortened to Krug. The colored sweater he chose for his villain was based on the DC Comics character Plastic Man. Craven chose to make Krueger's sweater red and green after reading an article in a 1982 "Scientific American" that said these two colors were the most clashing colors to the human retina.
