I orginally saw Dementia in 1972 at the Orson Welles Cinema in Cambridge Mass. It was there in error since Coppola's Dementia 13 was on the bill. What a treat. I requested return engagements after that and could find no reference to Dementia for years. Finally, at the library of arts at Lincoln Center in New York I found the history including the alternate title Daughter of Horror. I finally got a copy of the film about 6 years ago. Still one of my favorites. Particularly because of the music and the fabulous singing of Marnie Nixon (voice of Maria in West Side Story and other films. A brilliant film by John Parker - who may actually be Bruno Vesota. Unknown piece of information. He of course is famous for such classics as The Brain Eaters and Attack of the Giant Leeches. Seriously, Dementia is a great movie and displays a sophistication of production that belies its obvious lack of a substantial budget.
