I haven't seen it for years, but the vampire in a rocking chair bit definitely was in this film, and a couple of the other bits you mention are familar as well - although the iconic scene that everybody seems to remember is the vampire floating outside and tapping on the window.
Thank you Karis, Gulftastic, Sentenza, and jrmswfc so much. I looked up the trailer Salem's Lot and I seen some of the scenes in it I remember. I will be ordering Salem's Lot later thanks to all you guys. Looking foward to watching Salem's Lot . Many Thanks to you all and have a nice day.
