NIGHTMARE (1964)

 This is a pretty cool old psychological-type horror flick with some good creepy atmosphere and a few plot twists to keep things interesting.  It starts off as the story of a young girl who sees her mother kill someone right before her eyes making her a bit unhinged.  While this would later on become the plot to a zillion slasher movies here it's used to kick off what is sort of the Hammer studios version of the film DIABOLIQUE and I'm a big fan of that 50's French classic so a similarly well done thriller was a nice find.  One thing modern viewers might find strange is how well-behaved the crazy homicidal characters are in this.  I guess this musta been some kinda proper English thing.  Director Freddie Francis would go on to make a bunch of monster flicks for Hammer and most importantly TROG, the cult classic where JOAN CRAWFORD fights a killer caveman. NIGHTMARE is one of your blander titles but it's alternate, and also quite polite, U.K. title of HERE'S THE KNIFE, DEAR: NOW PLEASE USE IT is a more catchy one.
