I found this Mike. If you search for “Alternate Endings” on youtube, you will find a clip that shows you how the film should have ended. He basically goes outside with the vampires and tries to help him with the remedy.
There is a clip of a vampiry thing screaming at Mr Smith.. but I know exactly whihc one Steves talking about, and it wasnt in the theatrical release or DVD’s .. The one he’s on about resembled the alien in Alien 3 when it sniffs ripley int hospital
