Although Britain's Hammer Films is mostly known for their Gothic horrors (Frankenstein, Dracula, etc.), they also had a long series of "psycho" movies from "Scream of Fear" in 1962 to "Straight On 'til Morning" in 1973, which were in many ways even better (they definitely were by the 1970's) than their Gothics. This movie came fairly late in the cycle and perhaps isn't the best, but it is pretty decent. The story, as another reviewer said, is definitely "unusual". It isn't necessarily good and it isn't remotely believable, but it is certainly unusual. An American nurse (Stefanie Powers)comes to a secluded English mansion to care for the invalid adult son of a famous deceased composer. Right away she knows something is amiss. The sultry maid (Jane LaPortare)seems to have the guy addicted to drugs (and sex with her) and is using them to cruelly manipulate him. And SOMEBODY keeps playing the dead composer's music. . .The end is pretty absurd, but fun--and definitely surprising.
I had one big problem with this though. Apparently, they originally filmed this with some nude scenes by Stefanie Powers. Americans of a certain age will definitely remember Powers from the early 80's TV series "Hart to Hart" where she and Robert Wagner played husband-and-wife detectives. As Lionel Stander (who played the couple's butler "Max") said of her every week in the opening narration of the show: "She's GORGEOUS!!"-- which had to be the biggest understatement in the history of television. Anyway, some sick, depraved person seemed to have cut out her alleged nude scenes in the version I saw. Maybe some horny projectionist clipped them out and took them home for his, personal, um, use, but more likely it was someone trying to "protect society" (from what, God only knows). LaPortare (who is attractive, but a mere mortal compared to Powers) also seems to have received some unkind cuts, but she does have a brief nude swimming scene.
I don't mean to go on about this. It's still a worthwhile movie, but WHY must people do stuff like this?!
