John Saxon agreed to be in the film based on a poorly translated English version of the script, which omitted the cannibalism scenes and appeared to be a simple Vietnam War allegory. He found out about the actual content during filming, and was so shocked he briefly considered dropping out of the movie altogether. He never watched the finished film.
The film watched by Bukowski at the cinema is Nur drei kamen durch (1979), which starred May Heatherly, who plays the role of the infected nurse Helen.
Was one of the 39 films successfully prosecuted and banned in the UK as a "Video Nasty."
Giovanni Lombardo Radice (Charlie) and Ramiro Oliveros (Dr. Mendez) later died on the same date, April 27, 2023.
