Was a big influence on the Saw films
I read that James Wan is a fan of this film and many others and you can see the DNL references in Saw.
Such as Pighead in the red coat, Billy the puppet's cheeks having the spiral on the them like the ball on the floor at the beginning of DNL and Adam shaking on the floor at the end while the events of the film are shown and how they foreshadowed the ending.
