Wes Craven launched the A Nightmare on Elm Street horror franchise in 1984 with the introduction of Freddy Krueger, a burned dream-stalking killer. The series expanded through seven original films, a crossover with Jason Voorhees, and a 2010 reboot, cementing Freddy as a pop-culture icon. This influential slasher property transformed modern horror by blurring the line between dreams and reality.
