Crawlspace is a 1986 American horror thriller film starring Klaus Kinski as Karl Guenther, the crazed son of a Nazi doctor obsessed with trapping young women and slowly torturing them to death, alongside Talia Balsam, Barbara Whinnery, and Tané McClure. It is written and directed by David Schmoeller, and later became infamous due to the on-set conflicts between Schmoeller and Kinski, with claims that producer Roberto Bessi attempted to have Kinski murdered due to his continued hostility towards the crew.

Klaus Kinski was a German actor. Equally renowned for his intense performance style and notorious for his volatile personality, he appeared in over 130 film roles in a career that spanned 40 years, from 1948 to 1988. He is best known for starring in five films directed by Werner Herzog from 1972 to 1987, who would later chronicle their tumultuous relationship in the documentary My Best Fiend.
