The first thing that struck me about this movie and is often true of well done, low budget films is that it feels like a stage play. The movie is character and dialog driven with an economy of changing scenes. Like insects trapped in a magnifying jar, the claustrophobic space brings the characters into raw detail.
When I first saw this film, I thought it was foreign - maybe British, Canadian, or Italian. None of the actors have been in a lot of movies that I am aware of, although Starr has been in a few other B grade vampire movies (none near this good). Surprisingly it used to be easy to find for rent. Since it never came out on DVD though, it is tougher to find now (apparently it was released on laser disk but the second half/side was badly engineered so it would have to be remastered before being transferred).
There was however an uncredited remake in 1993: To Sleep With a Vampire (directed by Adam Friedman) that is available on DVD (for real cheap). It features almost the exact same script including portions of word for word dialog. Besides the fact that it is not as well acted, the main differences are that the stripper has bigger breasts and that both of the main characters had a small following before they took the rolls. Watching that remake is like watching your favorite play performed at a local High School: it reminds you pleasantly of the better performances you have seen.
