As might be expected from Dan OBannon, Hemoglobin/Bleeders is an interestingly complex, intelligent and well thought-out story, not unreminiscent in many ways of Edgar Allan Poes The Fall of the House of Usher (1839) and even more so of the H.P. Lovecraft story The Lurking Fear (1923). Unfortunately, the film falls down due to dreary direction. The photography is drab, while director Peter Svateks pace drags almost nothing happens in the first half-hour, for instance. One can see that a number of sequences have been designed on paper in a way that could have had some shock impact had they been directed by someone with half an ounce of talent creatures snatching bodies up from underneath coffins, Roy Dupuis having to devour a dead foetus but Peter Svatek directs them with a dreary lack of event. Indeed, in the case of the dead foetus devouring, the camera censuredly looks away when it comes to the act of doing so, which is surely a criminal lack of nerve for a horror film. A sex scene between Roy Dupuis and Kristin Lehman has never seemed more pointless and gratuitously inserted. It is only during the climax with the survivors huddled in a lighthouse during a rainstorm shooting off the monsters as they clamber up the cliffs that Peter Svatek manages to rouse anything approaching mild tension.
Director Peter Svatek had previously made Witchboard III: The Possession (1995) and Sci-Fighters (1996), although all of his work subsequent to Hemoglobin/Bleeders has been in television.
Screenwriter Dan OBannon also worked on Dark Star (1974) and the huge hit of Alien (1979). He subsequently turned in a series of excellent, cynical hard-edge genre scripts such as the zombie film Dead & Buried (1981), episodes of the adult animation anthology Heavy Metal (1981), the hi-tech helicopter action film Blue Thunder (1983), Tobe Hoopers soul-sucking alien vampire film Lifeforce (1985) and remake of Invaders from Mars (1986), and the Philip K. Dick adaptations Total Recall (1990) and Screamers (1995), as well as directing the zombie black comedy Return of the Living Dead (1985) and the H.P. Lovecraft adaptation The Resurrected (1992). Jodorowskys Dune (2013) details OBannons work as special effects director on Alejandro Jodorowskys failed adaptation of Dune (1965) in the 1970s.
