Spring-heeled Jack
A similar figure known as Pérák, the Spring Man of Prague was reported to have been seen in Czechoslovakia around 1939–1945. As writers such as Mike Dash have shown, the elusiveness and supernatural leaping abilities attributed to Pérák bear a close resemblance to those exhibited by Spring-heeled Jack, and distinct parallels can be drawn between the two entities. The stories of Pérák provide a useful example of how the traits of Spring-heeled Jack have a broad cultural resonance in urban folklore. Pérák, like Spring-heeled Jack, went on to become a folklore hero, even starring in several animated superhero cartoons, fighting the SS, the earliest of which is Jiří Trnka's 1946 film "Pérák a SS" or "Springman and the SS".
