Ernst Ritter von Theumer, a director and writer known for his work in the 1970s and 1980s, helmed the cult classic The Big Bust-Out (1972), where he also contributed as a writer. His knack for blending action and exploitation is further showcased in Jungle Warriors (1984), which he directed and wrote, cementing his role in the grindhouse genre. Von Theumer's distinctive style and thematic focus on adventure and survival resonate throughout his films, including Hell Hunters (1986), where he continued to explore the thrills of the action genre.
Island of the Doomed
A group of tourists arrive to see the botanical gardens on a small island off the Italian coast. The only inhabitants of the island are the famous botanist Baron von Weser and his two faithful servants; all of the other residents fled after a series of mysterious deaths. When the car driven by the tourists' guide hits one of the baron's servants, von Weser explains that the death was due to a rare and incurable disease, not the accident. That night, the guide and Cora Robinson, one of the guests, are found murdered with all the blood drained from their bodies.
