I have been trying for years to find out the name of a movie I saw around 1980 or 81. I was 12 or 13 at the time so I do not remember a whole lot. This is what I remember. I believe there where some sort of alien leech/worm things that were taking over an apartment complex. In one scene a lady was taking a bath and one of these alien things slowly crawled up out of the drain and slithered up between ........ At the end I think the creatures where in the basement or the indoor pool. I want to know what it was because I remember people actually vomiting in the theatre and many people were very offended and left. I think that I was so young that it went right over my head! People complained and the theatre stopped showing it. It was a double feature with Blood Beach. Anyway, I just wondered if anyone knew the title. Thanks!
