I'm recommending this b/w screen gem. Stars Janette Scott and the gorgeous Oliver Reed. A favorite scene in the film: It's birthday time again, and though we don't want to trigger any nasty memories for Eleanor [?] the cake is nonetheless wheeled out with a butcher knife to cut it with. :-P
I have a Hammer Film collection, 12 in all. Love Peter Cushing (those cheekbones -- *sigh*). Unfortunately Mr. Cushing is not in Paranoiac!
We might watch it this evening after the dinner party, whilst handing out goodies to the kids.
