Angst (English: "Fear") is a 1983 Austrian horror film directed by Gerald Kargl, who co-wrote the screenplay with cinematographer and editor Zbigniew Rybczyński. It follows a psychopath recently released from prison and is loosely based on real-life mass murderer Werner Kniesek. Though relatively obscure, the film was acclaimed for its camera work, score, and Erwin Leder's performance. It was banned all over Europe for extreme violence in 1983.
