The audio bit uses a Jackson sound-alike shouting, "I want these mother------- snakes off the mother------- plane!" Soon, the growing legion of fans added their voices as they demanded that that phrase also appear in the movie.
Apparently, the studio got the hint. When Ellis assembled Jackson and others for the recent shoot, the filmmakers added more gore, more death, more nudity, more snakes and more death scenes. And they shot a scene where Jackson does utter the line that fans have demanded.
