- UK video and DVD versions are cut by 5 seconds by the BBFC to remove shots of cock-fighting (illegal animal cruelty).
- A rare film clip from the original 1988 release shows Captain Peytraud entering the American clinic and standing over Dr. Alan after Alan has been poisoned. This clip did not make it into the final version of the film, which shows the entire scene from Dr. Alan's perspective looking up at Peytraud. Shots of Peytraud standing over Alan nevertheless appeared in publicity releases for the film as well as in Twilight Zone Magazine which featured an interview with author Wade Davis about the film.
