Trivia

Joan Crawford was approached for this film one month after she left Hush...Hush, Sweet Charlotte (1964) due to an "ailment" that prevented her from working (which is believed to have actually been sick of working with her arch enemy Bette Davis). Therefore, William Castle requested that Crawford's doctors sign a statement attesting that she was completely well before giving her the role. See more »

Quotes

Kit Austin: But at least I can come for dinner. He'll drive me over. How do we get there? You live out in the wilderness.
Libby: It's not that bad. It's easy really. You go about 15 miles past the gas station on Elm. Then you turn right on Tomkins Street. You keep going right until you pass the railroad tracks. Then you turn left and go for about 6 miles. You come to a red barn, you pass that...

Surprisingly Good
7 September 2009 | by on_the_canSee all my reviews

William Castle made a career out of monster and ghost stories, so even though the synopsis on my TV said this was a departure about teenage girls involved with murder I still expected the same kind of B-movie action. In truth though it was actually a pretty decent thriller.

A sixteen year old girl and her little sister who live in a secluded home a few miles away from anybody get the house to themselves for a night. The older girl invites her friend over for dinner and the three of them eventually resort to prank calling random people from the phone book to entertain themselves. Unfortunately for them they make the mistake of calling a man who's just committed murder and jokingly tell him, "I know what you did, and I know who you are." The man naturally assumes the voice on the line is serious and there is a witness out there who saw him disposing of his girlfriend's body. A variety of twists and intertwining characters eventually put the guilty man in the same room as our innocent kids.

The plot relies heavily on coincidence to stitch everything together and a major plot point hinges on an extremely stupid decision by our protagonists but in spite of it all, it still manages to build a lot of tension towards it's climax which although brief is handled very effectively. It also helps that this secluded home of there's is surrounded by forestry and continually deepening shadows as the night wares on with fog that's barely visible outside the moonlight, making for a very creepy and cool atmosphere. The acting is pretty good too, even our teenage heroes seem to exercise some decent chops all things considered. Good fun and good thrills.
