I saw this movie around 2005 – maybe a year earlier, no later than 2006. It was probably a straight to DVD release and I seem to remember it was probably a Liongate release. The opening scene or maybe even during the opening credits there were two topless women (I think they may have been demons). They were just sort of dancing, writhing, and crawling around. I think there was a bubbly,  gargly, or echoey type of voice saying something while they moved about. I don’t remember much else of the movie other than it was a horror movie. Thank you so much for your help!
