I know that many Fulci fans (among myself) would like to believe that Zombie III it's mainly a Bruno Matei film but it is not. Beatrice Ring has stated the opposite in many interviews (including one lengthy one in Dark Side magazine). Same thing can be found in THE definite book on Fulci, "Beyond Terror". Fulci finished a 75 minute cut of the film but some scenes dragged forever while others where short. Bruno Matei came in and filmed additional action scenes in just a few days to "save" the film. You wont find any official information that will state the opposite. Point is, Fulci had lost it and what we see in Zombie III is just the proof of that.
