Joan Saw What You Hung Your Clothes On...
30 May 2004 | by GroovyDoomSee all my reviews

and she knows who you are!

This is another strange William Castle concoction that features Joan Crawford in one of the B-horror movies she made near the end of her career, and yet the only way they could fit her into this story was to make her a kooky neighbor lady who wears tacky jewelry that looks like some sort of bizarre Aztec armor.

Everyone knows the plot, which involves two teenage girls who spend an evening making prank phone calls and, through the miracle of plot contrivance, stumble into the path of a psychotic man who has just committed murder.

I don't know if any of the other viewers felt the same way, but I really think the movie's violence is a bit shocking for its day. The first murder is an ironic ripoff of "Psycho", with the person in the shower committing the murder instead of being slashed, and I was surprised at how graphic it really is.

Also, I don't know whether this was really the filmmakers' intention or not, but they have captured the excitement of a teenage adventure and carried it effortlessly into a suspenseful conclusion. Ironically, the only thing in the movie that feels wrong is the subplot involving Crawford. It was obviously inserted to give the movie a star and to pad out the running time.
