Harrington also directed "Ruby", a pretty good possession thriller with Roger Davis (and Piper Laurie and Len Lesser). The DVD has completely inaccurate credits for Roger Davis, in which his credits were complied along with a silent film star of the same name, and gives the death date of the silent star. I once kidded Roger that I had picked up the disc, and thanked him for not letting his "death" prevent him from still attending conventions.
I met Curtis Harrington at a Fanex convention in Baltimore several years ago and he was an absolute delight, enthralling us with marvelous stories of working with many golden era Hollywood stars. He was very aproachable and seemed to be having a ball. I would probably say "Night Tide" is my favorite but I have such fond memories of watching "Queen of Blood" on old SciFi Theatre very late one Saturday as a kid.
One last tid-bit, a few years ago a friend purchased a vintage "Count Dracula Society" membership "kit" on Ebay and when he won it, and it arrived, it was Harrrington's personal kit.
Likewise, I think he was a talented and underrated fillmmaker. His movies are worth seeking out.
