this be a movie for anyone who love english horror film from the early 70 and that should mean you . a fog enshroud island and a derelict lighthouse and plenty of blood and sex and date slang oh yeah it here in abundance . don not listen to the other reviewer when they say this film would have be good if it have be make with today effect and a large budget . this film become well because it be make on a tighter budget and when the crew have to come up with inventive way to create atmosphere and menace and a sustained mood . all of these thing drip from every frame of this film and the cast be actually very good and even feature george couloris ( of citizen kane fame ) in a short but blood fill cameo at the start of the film and jill haworth and who have prior to this film star in such acclaimed flick a exodus and the broadway version of cabaret . forget those film though this be the highlight of her career everything else be just practice for this baby . some might say i be go too far but that would be wrong . the twist in this film be truly fun and surprising and the musical score add a real sense of unease to the well direct carnage and misty vista ( hat off to jim oconnolly . ) so what be you wait for this be now out on dvd and look crisp and vivid . get it and see how good horror film be not all that long ago .
