"throughout the production process Tom Six stated that his intention was to create a film that was 100% medically accurate, consulting a Dutch surgeon during the creation and filming process. Six claimed that while initially reluctant to take part in the film due to both concerns about professional reputation and feelings that the film had nothing to do with medical science, after reading the script the surgeon took a very strong interest in the procedure, and went on to devise a method that he believed would work in real life.Six claims that with this method, using an IV drip to supplement the diet of the middle and back parts would allow the centipede to survive for 'years'."
